I will not submit a patch, but I can explain what I meant. For instance
if termcap says the sequence for homing the cursor is "ESC [ H" or the
8bit equivalent, then you're probably dealing with an ANSI-compatible
terminal, that will happily either take heed or correctly parse and
ignore your bracketed paste sequence.

As I said, there might be a more direct way that I'm not aware of, but
this sounds like a clear indication making it easy to classify terminals
into ANSI and non-ANSI.

Of course a more direct alternative, assuming there aren't going to be
any new non-ANSI terminals coming out in the future (which is a good
bet), is to just build a list of known non-ANSI terminals, but that's
more work, and you might still miss some.
