Re: [PATCH 0/7] grep.c: teach --column to 'git-grep(1)'

Jeff King [off-list ref] writes:

Even if it's a double-inversion? The reason we carry both `col` and
`icol` is that it allows:

  git grep --not --not --not --not -e a

to still say "we found 'a' here". That's a dumb thing to ask for, but it
is true in the end that we show lines with "a" (and will colorize them
as such).

Yes.  I think the code is doing too much to cater to a dumb request
;-)
