regexprops-generic: update from regex.h * doc/regexprops-generic.texi: Re-generate by running the 'regexprops' binary from GNU findutils: ./regexprops "Regular Expressions" generic At least the recent(ish) change (efd5c380ff) to regex.h aligning gnulib with Emacs behavior had made this document out-of-date. Reported by Collin Funk in <https://lists.gnu.org/archive/html/bug-gnulib/2025-07/msg00037.html>. Additionally, today's findutils commit c9c2c51175 fixed the sort order of the Texinfo nodes.
