BTW I should have clarified why I decided on another name than regexecn()
(I had considered this even before reading Peff's proposed patch): the <n>
in string functions suggest a limiting of NUL-terminated strings. In other
words, if n = 100 and the provided pointer points to a NUL-terminated
string of length 3, the *n function will treat it as a string of length 3.
That is not what regexec_buf() does: it ignores the NUL. Hence the
