[Chicken-hackers] [PATCH] Irregex-fold infinite loop bugfix

Hello hackers,

The attached patch brings our irregex code up-to-date with the latest
fixes in upstream applied by Alex (also in the irregex-bugfixes branch).

It fixes a problem with irregex-fold that caused it to hang when it
matched an empty submatch, as shown by this simple code:
(irregex-fold '(* "a") void #f "ab")

"The process of preparing programs for a digital computer
 is especially attractive, not only because it can be economically
 and scientifically rewarding, but also because it can be an aesthetic
 experience much like composing poetry or music."
                                                        -- Donald Knuth
