What about it? The case of /usr/local/../../.. is handled correctly,
and the case where it's an underspecified relative path doesn't seem
that interesting to me --- certainly that is not so important that we
should get the wrong answer on cases that *are* plausible.
Most of the uses of canonicalize_path are on paths that are required to
be absolute, anyway.
It wouldn't be too implausible to error out if pending_strips>0 after
exiting the loop.
