Subject: [PATCH] Case-insensitive list matching fix

This fixes case-insensitive matching of lists in multi-byte character sets.
Original comment:

fix the following problem in multibyte locales.
 % echo Y | egrep -i '[y]'

>From aac37e1939632dbc7d2ade6f991af7ce103b0cba Mon Sep 17 00:00:00 2001
From: Tim Waugh <twaugh at redhat.com>

Subject: [PATCH] EGF Speedup

The full story behind this patch is that grep-2.5.1a does not handle UTF-8 gracefully at all. The basic plan with handling UTF-8 in 2.5.1a is:

    * whenever a buffer is parsed, go through the entire buffer deciding how many bytes make up each character
    * use this information when necessary

This patch changes that to:

    * when information about how many bytes make up a character is needed, work it out on demand

On the face of it, this is a small obvious improvement. In fact it is much better than that, because the original scheme would calculate character lengths several times for each buffer: in fact, one full pass for every single potential match!

For a full discussion of this patch, as well as dfa-optional, including benchmarking results, see the mailing list.

Subject: [PATCH] Fix line wrapping in PCRE backend

PCRE can't limit the matching to space between newlines (i.e
[^a] will allways match newline, see pcreposix(3) for details),
therefore whe have to split the buffer into lines and match each
line in the buffer separately.
