  either of both click_events or XTGETTCAP+indn is implemented.

- document properly that scrollback-push currently only works
  when XTGETTCAP+indn is implemented. There are still a few terminals
  that don't support SCROLL UP, for example the Linux Console,
  and there is no better way to find out if it's supported.
