Let's say we use BSD grep or Schilling grep or whatever - is there
actually any harm in exporting GREP_OPTIONS='--color=auto' in this

Yes, because if the grep implementation in question supports
GREP_OPTIONS
but doesn't support --color, you'll get errors when it's run.
(The assumption ... is that if --color is supported, then
GREP_OPTIONS is too, which is reasonable and is what happens for GNU
grep, although I cannot speak for other implementations).
So this keeps the .bashrc compatible with older versions of GNU grep.
That hadn't occurred to me.
My question is:
Do BSD & other greps also support GREP_OPTIONS ?
Stroller.
