[PATCH] dfa: check end of an input buffer after a transition in non-UTF8 multibyte locales |

If a state has neither ANYCHAR nor MBCSET and next character is eolbyte,
the next state is -1. So exit loop, checked whether a position is end
of buffer or not.
However, if a state has either ANYCHAR or MBCSET, even if next character
is eolbyte, next state mayn't be -1. So we must check whether a
position is end of buffer or not, otherwise may run over the buffer.
