<^C> is a plain "return" command now, while <^C^C> exits from the program
* This may break existing macros!
^C is now essentially a synonym for $$ and may not terminate the program
when called from a non-toplevel macro frame.
However it improves compatibility with TECO-11.
* In contrast to TECO-11, ^C^C (exit) can be typed completely in upcaret mode.
Otherwise it wouldn't have been possible to use the exit command in ASCII-only scripts.
* The implementation of ^C^C uses a lookahead state similar to ^[ (escape).
^C does not return immediately, but the following character determines whether it will
perform a return or exit.
It's one of the rare cases in SciTECO where this is possible and safe since
^C is also disallowed on the command-line to avoid undesired command-line terminations
after ^C interruptions.
(You can only use $$ to terminate the command-line interactively.)
