Huh? That's marginal for 'clear display', and just plain dumb for 'clear
scrollback'. The latter (which should have the same effect as '\e[3J', i.e.
toss out everything not on the screen) is extremely useful if you've, say, done
a build, ran 'clear', ran some other stuff, and now want to throw out the
scrollback of the build but need the other stuff still. Or even if you've just
run 'clear' and want to clear the scrollback also, but don't want your bash
prompt to disappear.

Actually I tend to think going behind the back of the running application and
clearing/resetting the screen is questionable.

I hope this will be reverted. (And I'm glad '\e[3J' still works; I am going to
be REALLY annoyed if that goes away :-). Which is to say, the code is still
there, there is just not a menu item for it any more.)

As for the original bug, I seem to recall this happening in early KDE4, but it
has been working correctly for quite some time. Works for me in trunk, anyway
(I am using "echo -e '\e[3J'" for step 4.)
