That would make them symmetric, but what I was driving at with "In
the context of testing git rm" was that I highly suspect that among
other existing users of test_path_is_missing there are some that
want to consider a dangling symbolic link as if it is not there (and
vice versa for test_path_exists), and it may not be a good idea to
unconditionally declare that, unlike the underlying "test" command
that dereferences symlinks for most operations, our wrapper does not
dereference symbolic links, which is what the "what do you think?"
patch and your addtion do.
