  1. grep: no match for empty pattern file 

    * Testing against old commit 504caa9, "grep -f empty" was handled by exit(1), i.e. no match
* A recent commit introduced a bug where ARGV would be shifted incorrectly if an empty file was passed as argument to -f
* Follow GNU grep and bypass the search in this case because we know there cannot be any matches

%touch empty && perl grep -f empty ar
%echo $?
