Here's the link: https://lists.gnu.org/archive/html/emacs-devel/2015-02/msg00362.html It offers 3 implementations. I think the second (group-folding-with-case-table-lisp.patch) was quite adequade. The only reason it wasn't applied is that Eli and Stefan wanted something that also matched non-spacing marks, or composite characters, whereas case tables can only map single characters to single characters. The first implementation (group-folding-with-regexp-lisp.patch) didn't have this caveat because it didn't use this case-tables. The only caveat it had is that it only works for non-regexp searches. Attached are the two patches I mentioned here.
