I don't agree with that. At least, I wouldn't obsolete them for
XEmacs. I think they're quite useful, and much faster than the
generic PREDICATE.

I have no statistics about that.

Please name your function differently to avoid confusion. I am
beginning to regret bringing this up.

Yes, please. For several days I ran my `locate-file' in place of
XEmacs's original (to shake out the bugs), and I noticed that
`sh-script' wouldn't load. That is because my locate-file found
contains "packages/sh-script" (a directory) before
"packages/sh-script/lisp/sh-script[.elc]" (a file).

I think it is ok for a function named `locate-file' to ignore
directories.
