grep: Fix -f FILE when FILE is empty and -x provided
Grep currently special-cased empty pattern file to be the same as pattern file with one empty line (empty pattern). That does mirror how GNU grep behaves, except when -x is provided. In that case .* pattern needs to be used instead. Signed-off-by: Gray Wolf <wolf@wolfsden.cz> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
