Unfortunately, Mr?/Ms? (I can't tell) Sasayama didn't give a description
of the symptoms of this bug. The symptoms are that `pr +N', where N
is a decimal integer, will always fail with the message
"pr: `+' requires a numeric argument".

Changing the above code fragment to:
		++s;
		if (!ISDIGIT (*s))
seems to fix the problem.
