I didn't write that.  Much though I appreciate being credited with
Merlyn's work, he said that, and I responded.

Hmph.

Uhm, not to be picky, but a distracted half-blind cat is significantl
faster than standard fgrep.

(Depends, though; whose fgrep is "standard"?  Also, on what kind of
match; I seem to recall that fgrep beat egrep on matching for any
of 200+ fixed strings, in a historical implementation.)
