1ee0dbee57 Fix a boundary condition error in slow() and fast() in multibyte locales:
we must allow the character beginning at "p" to be converted to a wide
character for the purposes of EOL processing and word-boundary matching.

0853006ff1 Change OUT from -2 to CHAR_MIN-1, making it impossible for it to
inadvertently match a negative char in the RE being compiled.

This fixes compilation of "\376" (as an ERE) and "\376\376" (as a BRE).

bd9643b135 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.

33176f1755 Fix two problems with REG_ICASE that were introduced with the addition of
multibyte character support:
- In CHadd(), avoid writing past the end of the character set bitmap when
  the opposite-case counterpart of wide characters with values less than
  NC have values greater than or equal to NC.
- In CHaddtype(), fix a braino that caused alphabetic characters to be
  added to all character classes! (but only with REG_ICASE)

e5996857ad Make regular expression matching aware of multibyte characters. The general
idea is that we perform multibyte->wide character conversion while parsing
and compiling, then convert byte sequences to wide characters when they're
needed for comparison and stepping through the string during execution.

As with tr(1), the main complication is to efficiently represent sets of
characters in bracket expressions. The old bitmap representation is replaced
by a bitmap for the first 256 characters combined with a vector of individual
wide characters, a vector of character ranges (for [A-Z] etc.), and a vector
of character classes (for [[:alpha:]] etc.).

One other point of interest is that although the Boyer-Moore algorithm had
to be disabled in the general multibyte case, it is still enabled for UTF-8
because of its self-synchronizing nature. This greatly speeds up matching
by reducing the number of multibyte conversions that need to be done.

8e2f75b833 The algorithm that computes the tables used in the BM search algorithm sometimes
access an array beyond it's length. This only happens in the last iteration of
a loop, and the value fetched is not used then, so the bug is a relatively
innocent one. Fix this by not fetching any value on the last iteration of said
loop.

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
