Subject: Collect sequences of printable ASCII characters and process them
 together instead of handling them one by one. This is significantly faster.
 Sequences are terminated when we reach the end of the line, fill the internal
 buffer, or a different character is seen by the input parser (an escape
 sequence, or UTF-8).

Rather than writing collected sequences out immediately, hold them until
it is necessary (another screen modification, or we consume all
available data). This means we can discard changes that would have no
effect (for example, lines that would just be scrolled off the screen or
cleared). This reduces the total amount of data we write out to the
terminal - not important for fast terminals, but a big help with slow
(like xterm).
