Hm.  But I guess people don't want to have that explicitly on the
command line they're editing when doing `M-x grep'?

The original problem was that the user had used a command that has
"less" as part of its pipeline, if running under a PTY.  Many other
commands react to the PTY in different ways (some that we want, like the
GREP_COLOR thing), and some that we don't want (like running less).

I'm not sure there's a fix here that will satisfy all use cases.
