[dev] [st] [PATCH] Clear the full screen on reverse terminal mode change.

[Colona]

Fix a bug introduced by 0dbf9c8c12a5de35d1cef22349ab80e8f0a8f10e
(introduction of term.dirty) which, on change of reverse mode (DECSCNM),
caused only dirty lines to be redrawn with the new mode instead of the
whole screen.
A good test-case is `echo foobar; tput flash`.
