'Esac' is a do-nothing command used to mark the end of a case statement.
It may be searched for by the 'case', 'when', or 'out' commands.
Every 'case' command must be followed by a matching 'esac' command.
.sp
'Esac' may be used to regain control of a terminal after execution
of a 'when' or 'out' command.
