Remove some options from 'hg grep':
-Z (we have -0 as in locate)
-a (use "-r 0:tip" instead, or always grep all unless -r is given)
-e (we have the PATTERN argument)
-v (doesn't work, and this is more of a job for 'hg cat|grep')
-s (we have -q/--quiet)
-f (should be always enabled if -l used, or enable on -v/--verbose)
