Seems sane. This way the strbuf is in the same state it was in before
calling this function (upon a failure that is).

There is another part of this function that returns NULL (which isn't
shown by this diff) after performing 'setup_git_dir_gently_1', do we
need to worry about anything that 'setup_git_dir_gently_1' has
potentially appended to 'gitdir' upon 'setup_git_dir_gently_1' failing?
