Yes, I think so. When I wrote my original posting, I was not sure
whether such a suggestion would be dismissed as unwished DWIM
behaviour, so I chose the more conservative suggestion.

I am not familiar with the intrinsics of the pathname system, so a silly
question about a possibly problematic case:

Let's say "/foo/bar" were a symlink pointing to a directory. Would
coercing that namestring to denote a directory correctly resolve the
symlink?
