bug#4115: grep and null device


From: ts011c8050
Subject: bug#4115: grep and null device
Date: Tue, 11 Aug 2009 09:41:50 +0100 (BST)
User-agent: SquirrelMail/1.4.3a

Using emacs 23.1.1 on Windows ( also saw it on emacs 22.x and upgraded )
grep is from cygwin "GNU grep 2.5.3"


Using rgrep always tags on a null device giving lots of output like

grep: NUL: No such file or directory
grep: NUL: No such file or directory
grep: NUL: No such file or directory
grep: NUL: No such file or directory
grep: NUL: No such file or directory

I've tried customising and turning of grep-use-null-device - as from a
quick look at grep.el this is responsible. But no success.

Bug recreated using -no-init-file and -no-site-file
