This is a first attempt to improve the comments of getopt_ulflags.c.
Maybe under some aspects the text could be refined, but so
far it is already usable and should help people who "avoided getopt_ulflags as the pest" to understand how it works.

This patch was created with the help of
Vodz, the author of the code, who explained me patiently
how getopt_ulflags works
and with the help of
Paul Fox, who corrected my broken english.

So thanks and merits should go to them also.
