No we cut it short by noticing that Emacs's internal state is the one we
expect and the display is completely wrong, which is something that
cannot happen due to some weird input sequence.

Please believe us, we *really* know that the problem is not in Emacs's
misunderstanding/misdecoding of the input stream (yes, it does have
bugs there, of course, but they're unrelated).

To repeat: replaying the termscript results in a different display (not
only that, it results in the display we want)!
This can't be due to Emacs's input processing.
