It sets up the normal git environment variables and a few helper
functions (currently just "die()"), and returns ok if it all looks like
a git archive. So use it something like
. git-sh-setup-script || die "Not a git archive"
to make the rest of the git scripts more careful and readable.

Sven Verdoolaege points out that I added the --verify option to
git-rev-parse exactly for things like this, but didn't update the
users.

The confusion between "revs" vs "refs" caused us to not find the branch
name, which in turn meant that we never switched the HEAD over to it.

Both of these scripts will end up resetting the index to some specific
head, and any unresolved merge will be forgotten.

The "${new=$old}" syntax only works for an undefined 'new', not for an
empty one. I knew that. Really. I'm not stupid.

Now "git checkout xyzzy" will check out branch "xyzzy" and
switch the HEAD to it.

And fix braino on testing "-f".
|
|

It is careful by default and refuses to overwrite old info, but if you
want to force everything to be re-read, use the "-f" flag.
Some day I'll make it take individual filenames too. Right now
it's all-or-nothing.
