Log Message:
Keep whole control strings out of the line buffer

restoreline() replays the line buffer to redraw a line after, for
example, a node message interrupts it. The line buffer already skipped
the body of a DCS/OSC/PM/APC string, but kept its "ESC _" introducer and
the final byte of its terminator. Replaying those opens a string the
terminal never sees closed, so it swallows all following output: an
@SOUND: in a prompt, followed by an incoming node message, was enough.

term_out() now records where each sequence begins in the line buffer and
rolls the buffer back to that point when a sequence completes, or breaks,
having been a control string. CSI sequences are left in place, so
restoreline() still restores colors.

ansi_parser_test.cpp pins the parser states this depends on.
