git-pickaxe: retire pickaxe

Just make it take over blame's place.  Documentation and command
have all stopped mentioning "git-pickaxe".  The built-in synonym
is left in the command table, so you can still say "git pickaxe",
but it probably is a good idea to retire it as well.

+SPECIFIYING RANGES
+------------------
+
+Unlike `git-blame` and `git-annotate` in older git, the extent
+of annotation can be limited to both line ranges and revision
+ranges.  When you are interested in finding the origin for

+range specifiers  similar to `git-rev-list`:
+
+	git blame v2.6.18.. -- foo
+	git blame --since=3.weeks -- foo
+
+When revision range specifiers are used to limit the annotation,
+lines that have not changed since the range boundary (either the
+commit v2.6.18 or the most recent commit that is more than 3
+weeks old in the above example) are blamed for that range
+boundary commit.
+
+A particularly useful way is to see if an added file have lines
+created by copy-and-paste from existing files.  Sometimes this
+indicates that the developer was being sloppy and did not
+refactor the code properly.  You can first find the commit that
+introduced the file with:
+
+	git log --diff-filter=A --pretty=short -- foo
+
+and then annotate the change between the commit and its
+parents, using `commit{caret}!` notation:
+
+	git blame -C -C -f $commit^! -- foo

-DESCRIPTION
------------
-
-Annotates each line in the given file with information from the revision which
-last modified the line. Optionally, start annotating from the given revision.
-
-Also it can limit the range of lines annotated.

-This report doesn't tell you anything about lines which have been deleted or
-replaced; you need to use a tool such as gitlink:git-diff[1] or the "pickaxe"
-interface briefly mentioned in the following paragraph.
-
-Apart from supporting file annotation, git also supports searching the
-development history for when a code snippet occured in a change. This makes it
-possible to track when a code snippet was added to a file, moved or copied
-between files, and eventually deleted or replaced. It works by searching for
-a text string in the diff. A small example:
-

-
--S, --rev-file <revs-file>::
-	Use revs from revs-file instead of calling gitlink:git-rev-list[1].
-
--f, --show-name::
-	Show filename in the original commit.  By default
-	filename is shown if there is any line that came from a
-	file with different name, due to rename detection.
-
--n, --show-number::
-	Show line number in the original commit (Default: off).
-
--p, --porcelain::
-	Show in a format designed for machine consumption.
-
--M::

-THE PORCELAIN FORMAT
---------------------
-
-In this format, each line is output after a header; the
-header at the minumum has the first line which has:
-
-- 40-byte SHA-1 of the commit the line is attributed to;
-- the line number of the line in the original file;
-- the line number of the line in the final file;
-- on a line that starts a group of line from a different
-  commit than the previous one, the number of lines in this
-  group.  On subsequent lines this field is absent.
-
-This header line is followed by the following information
-at least once for each commit:
-
-- author name ("author"), email ("author-mail"), time
-  ("author-time"), and timezone ("author-tz"); similarly
-  for committer.
-- filename in the commit the line is attributed to.
-- the first line of the commit log message ("summary").
-
-The contents of the actual line is output after the above
-header, prefixed by a TAB. This is to allow adding more
-header elements later.
