Previously, in -w mode, for each match on a line grep would check
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.
