Log Message:
awk.1: revert changes to example 'echo' program
I had removed the exit statement in the strong belief that POSIX had
specified that an AWK program consisting of only a BEGIN block would
implicitly exit after the BEGIN block. This assumption was wrong.
There are several implementations that implement this special case
though.
