Details:

grep 2.5.1 seems to not support the -P or --perl-regexp option, despite the
fact that these options are documented in the man page.

After reading another bug, "grep -P" doesn't support pattern lists"
(http://savannah.gnu.org/bugs/?func=detailitem&item_id=14946), I guess it is
the case that -P is broken.  Ideally, -P should be fixed!  If it can't be
fixed, there should be a mention of this in the man page.

I'm using grep 2.5.1-r8 on Gentoo and have perl 5.8.6 for i686 linux
installed.
