hidden (updated) Elisp to do the job

[Emanuel Berg via Users list for the GNU Emacs text editor <help-gnu-emacs@gnu.org>]

Here is even more Elisp for your viewing
pleasure. Keep up the good job!

And... what... does the first function _do_,
really?!

(PS. Save for the esoteric/dual feature, the
 other time file - mentioned - is more
 interesting. And more spooky... :) DS.)

But now, check out the new stuff first hand:

Or read it right here:
