grep-2.6.3 imminent: please test this snapshot

[Jim Meyering]

There is a bug in grep-2.6.2 that can make grep -F infloop.
I think we've addressed all of the pending problems except
one reported by Norihirio Tanaka (we're deliberately deferring
work on that, since it is so far out on the fringe of usefulness).

I would like to release grep-2.6.3 in a few hours,
so any feedback before then would be most welcome.

Here's the NEWS:
-------------------------------
** Bug fixes

  Searching with grep -F for an empty string in a multibyte locale
  would hang grep. [bug introduced in 2.6.2]

  PCRE support is once again detected on systems with <pcre/pcre.h>
  [bug introduced in 2.6.2]

And here's the snapshot info:
