This check we should retain and change the wording to mention '--and',
'--or', and '--not' specifically.

Agree that this is tricky. I don't think that --maybe-column is a
direction that we should take for the reasons I outlined in the cover
letter. Like I said, there are cases under an extended grammar where we
can and cannot display meaningful column offsets.
With regards to regressing 'git-jump', I feel as if 'git-jump --not' is
an uncommon-enough case that I would be comfortable with the tradeoff.
If a caller _is_ using '--not' in 'git-jump', they can reconfigure
'jump.grepCmd' to work around this issue.
Perhaps this is worth warning about in 'git-jump'? Peff, what do you
think?
Thanks,
Taylor
