Details:

On my Fedora 15 box, "grep x ." does not report an error,
even though (as strace shows) it reads "." and the read fails with
errno==EISDIR.  It should report an error.  I have submitted a proposed patch
for this in
<http://lists.gnu.org/archive/html/bug-grep/2011-12/msg00036.html>.

This bug was originally reported by Alan Curry in
<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10355#26> (for coreutils).
