Hi,

	Does anyone know how filename completion is implemented?  It
could not be in terms of "completing-read" since "completing-read" is
given an alist of completions beforehand while filename completion is
more dynamic. 

	One possible way of doing it is a completing read which is
given a function to be called instead of a static alist.  If this is
how it is done, are there primitives available?  Basically, I'd like
to implement REMOTE file name completion and I figure the easiest
thing to do is to emulate the way local filename completion is done.
