Interactive shell sequential commands: CTRL-C should cancel all commands

[pwt]

If you issue a sequential command in the interactive shell such as:

> wait_until 10:00 : line_in on

and then issue a CTRL-C to cancel the command, the wait_until is cancelled, but the line_in on will still execute. The desired behaviour is that the whole sequential command is cancelled.

Noe easy to fix!
