This was what I am looking for. But you have a number of pearls or
possibly bugs that I could not verify. Specifically, I am interested in a
dissection of the regular expression

and the conundrum is in \\{3\\}, a construct, which has no reference in
the info page on emacs regular expressions.
You may as well explain the wisdom in the use of
(save-excursion ; ???
(save-match-data ; ???
which I fail to see despite seeing description on them.
Thanks a lot!!!!
