Subject: [PATCH] t9903: Don't fail when run from path accessed through symlink
Message-ID: <20130411185322.GF14619@pvv.ntnu.no>
URL: https://gitlist.dev/e/20130411185322.GF14619%40pvv.ntnu.no

```
When the git directory is accessed through a symlink like

  ln -s /tmp/git /tmp/git-symlink
  cd /tmp/git-symlink/t
  make -C .. && ./t9903-bash-prompt.sh

$TRASH_DIRECTORY is /tmp/git-symlink/t/trash directory.t9903-bash-prompt
and $(pwd -P) is /tmp/git/t/trash directory.t9903-bash-prompt.

When __gitdir looks up the path through 'git rev-parse --git-dir', it
will return paths similar to $(pwd -P). This behavior is already tested in
t9903 'gitdir - resulting path avoids symlinks'.

Thanks, this makes sense to me, and is the same solution used in other
scripts (e.g., t2300), so I don't think we have to worry about any
portability concerns with "pwd -P".
