Summary

0004650: regexp_case_fold does not work correctly with an exclusion set

Description

When using an exclusion character set, regexp_case_fold produces incorrect results.

# #load "str.cma" ;;
# open Str ;;
# string_match (regexp_case_fold "[^a]") "a" 0 ;;
- : bool = true

This is due to the set being first "negated" (everything but 'a', including 'A') and applying case_fold afterwards. ('A' will lead to 'a' in the final set.)
