forked process doesn't terminate if there's an exec error #1

If the shell is given an external command that results in an "exec-error" message being printed on the screen, then control stays continues in the newly spawned forked process and doesn't terminate. If this happens several times, then many myshell processes litter the system and must be exited from individually.

Tentatively fixed -- added exit(-1) call after the print message
