Before going this route, could you expand on "hardwiring VT220 color
control codes would be bad"?  Are there any terminals we actually care
about that this would fail on?  (Note that the grep and ls maintainers
have both answered "no" to this question; search for the string '33['
in their source code.  ls at least appears to also have a whitelist
of $TERM values that are colorizable, dunno about grep.)
