Re-highlight windows when needed during TUI startup

I noticed that "tui enable" did not correctly show the source window
as having the focus.  Debugging showed that the problem was that
tui_update_variables was called after the windows were drawn, and its
result was being ignored.  This changed the code to re-highlight the
windows if the value changed.

	* tui/tui.c (tui_enable): Call tui_update_variables earlier.
