[RFC PATCH 2/2] Support shell scripts that run from symlinks into a git working dir

["Marcel M. Cary" <marcel@oak.homeunix.org>]

Use "cd -P" instead of just "cd" when switching to the top level
of the git working directory.  When working from a symlink
into GIT_WORK_TREE, the shell function cd_to_toplevel will now
change to GIT_WORK_TREE rather than the parent of the symlink,
which may not even be the root of a git working directory.

Unfortunately this solution looks non-portable.
