unless I missed a response, so far all that's been demonstrated is that a
newer version of GNU grep doesn't behave the same as other versions of
grep.  It's probably a bug rather than a feature (bear in mind that
GNU grep has to keep track of whether it's supposed to be fgrep, grep or
egrep -- in the latter case, `+' would be a metacharacter).
