implemented the <^A> command for printing arbitrary strings
* Greatly improved usability as a scripting language.
* The command is in DEC TECO, but in contrast to DEC TECO, we also
support string building constructs in ^A.
* Required some refactoring: As we want it to write everything verbatim
to stdout, the per-interface method is now teco_interface_msg_literal()
and it has to deal with unprintable characters.
When displaying in the UI, we use teco_curses_format_str() and TecoGtkLabel
functions/widgets to deal with possible control codes.
* Numbers printed with `=` have to be written with a trailing linefeed,
which would also be visible as a reverse "LF" in the UI.
Not sure whether this is acceptable - the alternative would be to strip
the strings before displaying them.
* Messages written to stdout are also auto-flushed at the moment.
In the future we might want to put flushing under control of the language.
Perhaps :^A could inhibit the flushing.
