I still don't understand one thing -

The problem is now fixed, right?

It appears that it's still using a very hacky regexp - see (defvar directory-listing-before-filename-regexp...) during file deletion.
which does all kinds of hacky checks, guessing where the timestring ends and where the filename begins.

(A) So, is this still a hack? 

(B) Is the problem fixed for good, or can one still concoct edge cases?
(C) If it is fixed, then why does that regex need this massive hack?
