It would sometimes be nice to be able to clear PuTTY's scrollback from
the server (via an escape sequence). Example applications:
- Terminal locking software (e.g. screen's C-a C-x) could
issue this escape sequence.
- If a lot of output is generated it makes use of the scrollback as
a poor man's less easier.
Recent versions of
xterm use an extension to ED to do
this, in the form of CSI
J. We could do

scrollback in xterm - it doesn't have any other effect.
