Did you tried this on different systems? In the documentation of path_concat
the 2nd argument should be a basename and not a relative path in
Unix-notation.

Therefor I would not recommend to use your construction instead of path_rel.
Of course it fails for me in a very simple case: r= "..".

Actually path_rel relies completly on path_concat and path_dirname. The
relative
path gets evaluated subsequently and each ".." calls path_dirname and each
basename
calls path_concat.

The intention for path_rel is to handle a system-independant relative file
specification
(e.g. "a/b/c") of any arbitrary length in a painless way.
