        src/bin/sh: eval.c

Log Message:
POSIX says that the arg to break or continue is to be a positive integer
(by which they mean > 0).  We were checking for negative numbers, but
not for 0.  More by chance of the implementation than any specific design
(I suspect) "break 0" was being treated the same as "break" or "break 1".
Since 3 ways to achieve the same thing is overkill, let's do what posix
wants and forbid "break 0" and "continue 0".
