+Subject: Relax parameter validation for various functions
+
+Following some deliberation over the matter, I have concluded that
+calling die() for the handling of invalid parameters ought not to be
+considered as a matter of course. As such, this commit retains the
+existing diagnostics for the functions listed below, while modifying
+them so as to no longer attempt to exit the shell.
