No, that would imply reverting the change which is unlikely to happen
(and cause a further breaking change for anyone relying on the new
behaviour). I want to know how to emulate the old behaviour, as this
isn't obvious. My only solution is to wrap grep in a macro that parses
its arguments, and passes -r only if paths have been provided on the
command line.
