The fix is to put 'exit(2)' after the line

	fprintf(stderr, "RE botch\n");

in compile(), and the line

	fprintf(stderr, "RE error\n");

in advance(). This only applies to /usr/ucb/grep in 4.2 and 4.3.
Without these, you get an 'RE error' message followed by a whole
slew of 'RE botch' messages. There isn't any reason for grep to
keep going if the RE compiles wrong, anyway.

Admittedly, when I first saw this bug reported, I fired off a note
to Narendra saying it wasn't a bug. Like a fool (sorry Barry), I
didn't try it out first (I did this last year as well, an event Dave
Sherman may remember).
