Hi Paul,

All in the name of quality.  I appreciate the feedback. (:

Why bother looking for gfgrep and gegrep?  As it stands, the code
always prefers a GNU grep to a non-GNU grep, so it will find (say)
ggrep, and since GNU grep supports -E it will always use "ggrep -E"
instead of "gegrep".  Therefore, there's no reason to look for gegrep.
Similarly for gfgrep.

It seems more orthogonal (to sed/gsed, grep/ggrep), and maybe someone
installed GNU egrep as gegrep, but not ggrep or gfgrep?  I know that's
stretching it a bit, but why not try and work in that situation too when
it doesn't cost anything?

I don't have a strong feeling either way really, just trying to be even
handed (-:

Anyway, I merged your cmp->diff patch, and fixed some latent bugs with
cache var handling.  Here's the result (with g{e,f}grep removed).

Okay to apply?


P.S. I can't do anymore revisions of this patch, because I don't know the
