I would think that the default behavior should be to resolve symbolic
links.  To better handle symbolic links, several functions could be
added, which might include is_symbolic_link, resolve_relative (or
resolve_relatively), which works the same way as readlink, and resolve
(or resolve_absolute or resolve_absolutely or resolve_complete), which
would be equivalent to complete(resolve_relative(ph), ph).  In
addition, it would be useful to have a function unresolved(path) or
dont_resolve(path) which returns a path wrapped such that the various
functions do not resolve it if it is a symbolic link.
