Prior to this commit, the cleanup trap that removes the tmp dir
created by the script would fail on Windows. The error was silently
ignored by the script.
On Windows, a directory cannot be removed while it is the working
directory of the process (thanks to Johannes Sixt on the Git list
for this info [1]).
This commit eliminates the 'cd' into the tmp directory that caused
the error.

There were 3 instances of a 'while read; do' that used identical logic
to populate '/tmp/right_dir'. This commit groups them into a single loop.

The 'tar' utility is not available on all platforms (some only support
'gnutar'). An earlier commit created a work-around for this problem,
but a better solution is to eliminate the use of 'tar' completely.

Config option diff.statGraphWidth=<width> is equivalent to
--stat-graph-width=<width>, except that the config option is ignored
by format-patch.
For the graph-width limiting to be usable, it should happen
'automatically' once configured, hence the config option.
Nevertheless, graph width limiting only makes sense when used on a
wide terminal, so it should not influence the output of format-patch,
which adheres to the 80-column standard.

The 'git difftool' allows the user to view diffs using an external tool.
It runs a separate instance of the tool for each file in the diff. This
makes it tedious to review changes spanning multiple files.
The 'git-diffall' script instead prepares temporary directories with the
files to be compared and launches a single instance of the external diff
tool to view them (i.e. a directory diff).
The 'diff.tool' or 'merge.tool' configuration variable is used to specify
which external tool is used.

The style used for incrementing and decrementing variables was fairly
inconsistenty and was normalized to use x++, or ((x++)) in contexts
where the former would otherwise be interpreted as a command. This is a
bash-ism, but for obvious reasons this script is already bash-specific.

When the --use-client-spec is given to clone, and the clone
path is a subset of the full tree as specified in the client,
future submits will go to the wrong place.
Factor out getClientSpec() so both clone/sync and submit can
use it. Introduce getClientRoot() that is needed for the client
spec case, and use it instead of p4Where().
Test the five possible submit behaviors (add, modify, rename,
copy, delete).

RCS keywords cause problems for git-p4 as perforce always
expands them (if +k is set) and so when applying the patch,
git reports that the files have been modified by both sides,
when in fact they haven't.
This change means that when git-p4 detects a problem applying
a patch, it will check to see if keyword expansion could be
the culprit. If it is, it strips the keywords in the p4
repository so that they match what git is expecting. It then
has another go at applying the patch.
This behaviour is enabled with a new git-p4 configuration
option and is off by default.

Currently we only bother highlighting single-line hunks. The
rationale was that the purpose of highlighting is to point
out small changes between two similar lines that are
otherwise hard to see. However, that meant we missed similar
cases where two lines were changed together, like:
-foo(buf);
-bar(buf);
+foo(obj->buf);
+bar(obj->buf);
Each of those changes is simple, and would benefit from
highlighting (the "obj->" parts in this case).
This patch considers whole hunks at a time. For now, we
consider only the case where the hunk has the same number of
removed and added lines, and assume that the lines from each
segment correspond one-to-one. While this is just a
heuristic, in practice it seems to generate sensible
results (especially because we now omit highlighting on
completely-changed lines, so when our heuristic is wrong, we
tend to avoid highlighting at all).
Based on an original idea and implementation by Michał
Kiedrowicz.

The current code structure assumes that we will only look at
a pair of lines at any given time, and that the end result
should always be to output that pair. However, we want to
eventually handle multi-line hunks, which will involve
collating pairs of removed/added lines. Let's refactor the
code to return highlighted pairs instead of printing them.

If you have a change like:
-foo
+bar
we end up highlighting the entirety of both lines (since the
whole thing is changed). But the point of diff highlighting
is to pinpoint the specific change in a pair of lines that
are mostly identical. In this case, the highlighting is just
noise, since there is nothing to pinpoint, and we are better
off doing nothing.
The implementation looks for "interesting" pairs by checking
to see whether they actually have a matching prefix or
suffix that does not simply consist of colorization and
whitespace. However, the implementation makes it easy to
plug in other heuristics, too, like:
1. Depending on the source material, the set of "boring"
characters could be tweaked to include language-specific
stuff (like braces or semicolons for C).
2. Instead of saying "an interesting line has at least one
character of prefix or suffix", we could require that
less than N percent of the line be highlighted.
The simple "ignore whitespace, and highlight if there are
any matched characters" implemented by this patch seems to
give good results on git.git. I'll leave experimentation
with other heuristics to somebody who has a dataset that
does not look good with the current code.

Kiedrowicz.

If the argument for `__git_ps1` begins with a dash, `printf` tries to
interpret it as an option which results in an error message.
The problem is solved by adding '--' before the argument to tell
`printf` to not interpret the following argument as an option.
Adding '--' directly to the argument does not help because the argument
is enclosed by double quotes.

When listing commands in zsh (git <TAB><TAB>), all of them will show up,
instead of only porcelain ones.
The root cause of this is because zsh versions from 4.3.0 to present
(4.3.15) do not correctly propagate the SH_WORD_SPLIT option into the
subshell in ${foo:=$(bar)} expressions. Because of this bug, the list of
all commands was treated as a single word in __git_list_porcelain_commands
and did not match any of the patterns that would usually cause plumbing to
be excluded.
With problematic versions of zsh, after running
emulate sh
fn () {
var='one two'
for v in $var; do echo $v; done
}
x=$(fn)
: ${y=$(fn)}
printing "$x" results in two lines as expected, but printing "$y" results
in a single line because $var is expanded as a single word when evaluating
fn to compute y.
So avoid the construct, and use an explicit 'test -n "$foo" || foo=$(bar)'
instead.

This simplifies svn-fe a great deal and fulfills a longstanding wish:
support for dumps with deltas in them, and incremental imports.
The cost is that commandline usage of the svn-fe tool becomes a little
more complicated since it no longer keeps state itself but instead reads
blobs back from fast-import in order to copy them between revisions and
apply deltas to them.
Also removes a couple of custom data structures and replaces them with
strbufs like other parts of Git.

Handle input in Subversion's dumpfile format, version 3. This is the
format produced by "svnrdump dump" and "svnadmin dump --deltas", and
the main difference between v3 dumpfiles and the dumpfiles already
handled is that these can include nodes whose properties and text are
expressed relative to some other node.
To handle such nodes, we find which node the text and properties are
based on, handle its property changes, use the cat-blob command to
request the basis blob from the fast-import backend, use the
svndiff0_apply() helper to apply the text delta on the fly, writing
output to a temporary file, and then measure that postimage file's
length and write its content to the fast-import stream.
The temporary postimage file is shared between delta-using nodes to
avoid some file system overhead.
The svn-fe interface needs to be more complicated to accomodate the
backward flow of information from the fast-import backend to svn-fe.
The backflow fd is not needed when parsing streams without deltas,
though, so existing scripts using svn-fe on v2 dumps should
continue to work.
NEEDSWORK: generalize interface so caller sets the backflow fd, close
temporary file before exiting

This teaches svn-fe to incrementally import into an existing
repository (at last!) at the expense of less convenient UI. Think of
it as growing pains. This opens the door to many excellent things,
and it would be a bad idea to discourage people from building on it
for much longer.
* db/vcs-svn-incremental:
vcs-svn: avoid using ls command twice
vcs-svn: use mark from previous import for parent commit
vcs-svn: handle filenames with dq correctly
vcs-svn: quote paths correctly for ls command
vcs-svn: eliminate repo_tree structure
vcs-svn: add a comment before each commit
vcs-svn: save marks for imported commits
vcs-svn: use higher mark numbers for blobs
vcs-svn: set up channel to read fast-import cat-blob response

Set up some plumbing: teach the svndump lib to pass a file descriptor
number to the fast_export lib, representing where cat-blob/ls
responses can be read from, and add a get_response_line helper
function to the fast_export lib to read a line from that file.
Unfortunately this means that svn-fe needs file descriptor 3 to be
redirected from somewhere (preferrably the cat-blob stream of a
fast-import backend); otherwise it will fail:
$ svndump <path> | svn-fe
fatal: cannot read from file descriptor 3: Bad file descriptor
For the moment, "svn-fe 3</dev/null" works as a workaround but it
will not work for very long. A fast-import backend that can retrieve
old commits is needed in order to be able to fulfill svn
"Node-copyfrom-rev" requests that refer to revs from a previous run.
