Commit Message

grep: fix logic for empty patterns

* Checking length of $pattern is unreliable because it is valid for a pattern to have zero-length (meaning match-all)
* I found this when testing the -f option but the logic applies to other usages of grep

%md5sum a.c
c9fd7ff4cb5b01981a2a362f82f44c89  a.c
%perl grep -F '' a.c | md5sum 
c9fd7ff4cb5b01981a2a362f82f44c89  -
%printf "\n" > pat0 && perl grep -f pat0 a.c | md5sum 
c9fd7ff4cb5b01981a2a362f82f44c89  -
%perl grep -e '' a.c | md5sum
