Where exactly would you want the predicate to be specified?
In the partial-completion-mode code? (Like in the attached patch?)
Or in read-file-name?

The predicate is _not_ specified by the partial-completion-mode code!
It is set by this code in read-file-name:
specbind (intern ("read-file-name-predicate"),
(NILP (predicate) ? Qfile_exists_p : predicate));
If you look in one of my messages in this thread:
PC-do-completion calls test-completions that calls
read-file-name-internal which returns Qnil because of this code:
if (!NILP (Vread_file_name_predicate))
return call1 (Vread_file_name_predicate, string);
read-file-name-predicate was bound to
file-exists-p in read-file-name,
and (file-exists-p "/tmp/DELETEME") return nil.
This patch fixes the original problem. Is this the correct fix? (I am
not sure it is)
