Since git-rev-parse already checks for the $GIT_DIR environment variable and that it returns an actual git repository, there is no need to repeat the checks again here. This also fixes a problem where git-svn did not work in cases where .git was a file with a gitdir: link. [ew: squashed test case, delay setting GIT_DIR until after `git rev-parse --cdup` to fix t9101, (thanks to Junio)] Signed-off-by: Barry Wardell <barry.wardell@gmail.com> Signed-off-by: Eric Wong <normalperson@yhbt.net>
