delayed so options that affect pattern-building (such as -w) can be
applied evenly to all such patterns.
ok and help otto, ok millert

using the -w option with parentheses, to avoid operators in the
expressions binding to the markers. Compare [[:<:]]foo|bar[[:>:]]
and [[:<:]](foo|bar)[[:>:]]. Problem spotted by aaron@; ok millert@

(PR 3940, 3941) which can be fixed, but if a match starts at the
end of a block and continues into the next block, no match will be
found. Measurements by millert@ showed that the improvements of
this optimization are non-measurable anyway. Diff from Alexander Taler.

fastcomp. This makes fgrep faster and fixes the -w flag w/ fgrep.
Also remove free_patterns() since calling free right before exit
is silly. Problem noticed by espie@

With this change we pass the updated regress. Tested and OK by ho@

to see if the match was on a word boundary. However, this missed
lines where the first match was not on a word boundary but a
subsequent match was. Problem originally spotted by miod@
We fix this by using the [[:<:]] and [[:>:]] character classes for
the slow path and by checking the word boundaries in grep_search()
for the fast path instead of doing the checks after running
regexec() or grep_search().
With this change, grep passes the new regress tests 15 and 16.

the fact that optind refers to the *next* argument to be consumed
by getopt(), not the current one. This means we have to keep track
of when we are working with a new argv entry by hand. OK hugh@

Fixes a problem on sparc64 where sizeof(int) != sizeof(pointer).
Based on a patch from Brian Poole; tedu@ OK

keep track of what the last char from getopt was as well as the
previous value of optind so we know when a new number has started.

o maxPatternLen should be size_t since that's what it is compared against
o remove useless casts of NULL to various pointer types

this makes searching for constant strings much faster by avoiding regex.

slow because libc regexp is slow. Anyone out there have the balls to sit
down and optimize libc regexp?
