[PATCH] GIT: Honour SHA1_FILE_DIRECTORY env var in git-pull-script

If you set SHA1_FILE_DIRECTORY to something else than .git/objects
git-pull-script will store the fetched files in a location the rest of
the tools does not expect.

git-prune-script also ignores this setting, but I think this is good,
because pruning a shared tree to fit a single project means throwing
away a lot of useful data. :-)
