* src/vte.c: Don't send motion-tracking events to the child unless
	we're dragging.  Fix ce so that it works even right after startup.
	Make sure that repainting the entire window actually exposes the
	visible parts of the window.  Fix tab clearing to also allow removal of
	the current tabstop.  Implement save-mode and restore-mode.  Start on
	reverse-video mode.  Don't scroll on modifier keypress events.  Rework
	part of clipboard copy.
	* termcaps/xterm: Add missing F11/F12/End keysyms to bundled xterm
	termcap.
