Re: convert regex.c, strftime.c mktime.c to standard C

    But I wonder what the performance impact would be if functions like
    `re-search-forward' just moved the gap somewhere (to before point, for
    instance?).  Then the regex functions could just work directly on the
    buffer, but without knowledge of the gap.  

Most editing is localized.  With a large buffer, it would be a big
inefficiency to move the gap far away for each search, then move it back
to change the buffer.
