updated for version 7.4.292
Problem: Searching for "a" does not match accented "a" with new regexp
engine, does match with old engine. (David B?rgin)
"ca" does not match "ca" with accented "a" with either engine.
Solution: Change the old engine, check for following composing character
also for single-byte patterns.
