bug#19252: [PATCH] dfa: matching at next position or infinit loop in matching mode

[Norihiro Tanaka]

After failed to match in matching mode, dfa transits initial state
when not allow newline or next state when allow new line instead of
return NULL.

That will cause next matching at position or infinit loop.  By the
way, theere is no affair for grep in order that it always uses not
matching mode but searching mode.

First patch fixes the bug, and second patch simplifies around the code.
