Ouch. Somehow there are duplicates under CLISP indeed. WTF? That might
have been one of the reasons the code was factored that way to begin
with, for all I remember of the pains of writing UIOP.
Maybe I should keep the remove-duplicates, just use 'equal for
physical pathnames and 'pathname-equal for logical pathnames? Maybe
only for CLISP? This seems to fix the bug. Should I commit and push?

Whenever someone asks what I think government rulers should do, my answer is
that it should follow the example of the only honest ruler ever, Oedipus:
they should apologize for their sins, step down, and gouge their own eyes out.
