Details:

Please verify these cases to work both with the _unmodified_ most recent
source:

perl -e '@a=qw/abc def ghi/; foreach(@a){print "$_\n"}' | grep ^def
prints def\n - OK

perl -e '@a=qw/abc def ghi/; foreach(@a){print "$_\0"}' | grep -z ^def

prints NOTHING. FAIL. grep -z -x 'def.*' however works. 

This failure is IMHO a critical error, as the -z option is probably
frequently used for backups and system admin scripts.

grep 2.5.3, Ubuntu jaunty amd64 (2.5.3~dfsg-6ubuntu1; the error might be
recently introduced (downstream issue?) as I haven't observed it before)

LANG=en_US.UTF-8, no LC* being set yet.

Thanx,
Peter.
