Add "git-sh-setup-script" for common git shell script setup 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. 20 years ago			`#!/bin/sh`

[PATCH] Make .git directory validation code test HEAD Inspired by a report by Kalle Valo, this changes git-sh-setup-script and the "setup_git_directory()" function to test that $GIT_DIR/HEAD is a symlink, since a number of core git features depend on that these days. We used to allow a regular file there, but git-fsck-cache has been complaining about that for a while, and anything that uses branches depends on the HEAD file being a symlink, so let's just encode that as a fundamental requirement. Before, a non-symlink HEAD file would appear to work, but have subtle bugs like not having the HEAD show up as a valid reference (because it wasn't under "refs"). Now, we will complain loudly, and the user can fix it up trivially instead of getting strange behaviour. This also removes the tests for "$GIT_DIR" and "$GIT_OBJECT_DIRECTORY" being directories, since the other tests will implicitly test for that anyway (ie the tests for HEAD, refs and 00 would fail).

[PATCH] Make git-sh-setup-script do what it was supposed to do Duh. A missing && meant that half the tests that git-sh-setup-script were _meant_ to do were actually totally ignored. In particular, the git sanity checking ended up only testing that the GIT_OBJECT_DIRECTORY was sane, not that GIT_DIR itself was..
