Negative lookahead context!? You are several sigmas beyond the subset
of regex functionality that \d and friends are intended to support.
Given that we're defining * and ? as shell-style wildcards, it's not
going to be feasible to handle very much of ordinary regex usage let
alone advanced.

This on the other hand seems more like a potentially useful feature,
although I'm unclear on what you expect to get sent through the pipe
exactly --- you want column headers for instance? What if you're using
a nondefault display layout?
