Finding the actual name (I wouldn't call it "canonical",
since that term could be ambiguous) requires reading the
contents of entire directories at each step, which could
be noticeably less efficient than what realpath() currently
does. Users who only want symlinks expanded might object
to that.

An option could be added to realpath(), but then we're
into constant-parameter territory.
