vim: src/regexp_nfa.c annotate

annotate src/regexp_nfa.c @ 4726:3849c811cc0b v7.3.1110

updated for version 7.3.1110 Problem: New regexp matching: Using \@= and the like can be slow. Solution: Decide whether to first try matching the zero-wdith part or what follows, whatever is more likely to fail.
