That (as in, gnu grep) should be fixed.  There's no reason not
to use grep -E on systems that have it, and similarly no reason
not to use egrep (or fgrep) on systems that have it (or them).

egrep is 2 chars less to type than grep -E, and does not involve
use of the shift key.  It is also traditional.  Issuing warnings
for using it is insane.
