Hi Jim,

I have one patch.  It fixes the bug which waste a lot of memory in
dfamust() for a very large pattern.  Now, I will send it.

> There's also Bug#16586 which is marked as important but which I can't 
> reproduce.

It reproduces as following.

/usr/bin/printf "\xe9\x65\n\xab\n" | env LC_ALL=en_US.utf8 grep -P '.e|.?z' | 

However, I seem that it's a bug of PCRE library.  PCRE library may
assume that a text doesn't have invalid sequence in UTF-8.
