Re: [Xsb-development] Dealing with pathnames

[Michael K. <ki...@cs...>]

This code underwent some changes since I first wrote it, but the reason I
think was that tilde_expand_filename is only one of the cases considered in
expand_filename (where you go to the password file, etc.)  If you see how
these can be simplified -- go ahead.

The other question probably is why should tilde_expand_filename be exposed
to Prolog as a builtin. That I don't know. It is used twice in the loader,
but I am not sure why expand_filename is not used instead.
