Ctrl-AJ (clear to EOS)
Ctrl-A` (home cursor)

Oct-14-2018:
It turns out, PabloDraw actually inserts a Ctrl-AZ sequence at the end of .msg
(and presumably Synchronet .asc) files it edits - before the SAUCE record.
This resulted in a printed Ctrl-Z character (arrow pointing right) in most
terminals when viewing text/menu files created or edited with PabloDraw. :-(
So, now Ctrl-AZ (uppercase) will revert to the previous definition:
premature end-of-file (EOF)
and a Ctrl-Az (lowercase) will output a Ctrl-Z (substitute) character.
I'm not a big fan of case-sensitive Ctrl-A codes, but frankly, running out of
chars and I already started this pattern with the Ctrl-AF/f sequences.
Hopefully there's no existing software that is/was putting Ctrl-Az (lowercase)
in files, expecting that to trigger a premature EOF. I certainly was not.

when sending the "ANSI" output to stdout (and not a file).

was so pervasive. I hope I don't regret changing this. Ctrl-AZ == Ctrl-Z just
"feels right" while Ctrl-AZ == EOF feels stoopid. :-/

equivalents (e.g. pause, delay).

Fixed handling of Ctrl-A\x7F (invalid code).
Ctrl-A\x80 now translates to <ESC>[C rather than <ESC>[1C.
Ctrl-AL now translatest to <ESC>[2J<ESC>[H to more ANSI-correct.

Allow a - to indicate that stdio should be used as input/output.

confusion.
