Indeed, looking at git-rev-parse(1), the correct option might be
--show-toplevel, which will print the cwd if it is the top-level of a
non-bare repository:
cd $candidate && test $(git rev-parse --show-toplevel) = $candidate
or
test $(git --git-dir=$candidate rev-parse --show-toplevel) = $candidate
Of course Git will resolve symlinks at this point, so $candidate has
to be resolved first for the equality to make sense.
Other solution is to parse the "gitdir: ..." format and recurse, which
is not exactly hard (provided you speak Tcl).
