I actually had complained about this nonsense in the grep bug channel (a
mailing list),
and Eric had responded there, my further reply being pending... so let
me put it here for now;
I've read the POSIX definition of "binary file" that was quoted in the
grep bug already,
and if I remember correctly (or how this is abbreviated here...) it does
not mention character encoding or locale.
In any case the argument is quite artificial since the new behaviour
hits many files that are in fact text files.
Thus it is very undesirable from any reasonable users' point of view,
which should be the guideline for software design rather than dogmatic
locale theories. Therefore I hold the claim that this is a serious flaw
in grep and I hope it will be reverted.
