  Log:
  Fix computation of the 'n' argument to mbrtowc (through XMBRTOWC) to avoid
  reading past 'stop' in various places when converting multibyte characters.
  Reading too far caused truncation to not be detected when it should have
  been, eventually causing regexec() to loop infinitely in with certain
  combinations of patterns and strings in multibyte locales.
