In dfaexec(), if reaches at eolbyte, we can skip checking of multibyte
character boundary.  So then process mbp until here.

Thanks, I installed that.  The "mbp = p" assignment can be done 
unconditionally.  Some of the other code in the neighborhood can stand 
some minor cleanups too, so I did that as per the attached patches.
