Too late.  GNU grep already has --recursive.  I think adding
--recursive to grep was a mistake.  It then requires most of 'find' to
be added to it too.  (--include*, --exclude*)

All silently.  For most cases I think your example would have been a a
case of programming error.  It would be better to make those cases noisy.

The above seems to be a bug since it violates the documented action of
'read' for directories.  It appears to be skipping by default.  Even
when --directories=read is specified.

And the problems just go on and on.
