Disposition: Fixed 12-sep-84. An off by one in MOVEDSMAP caused by adding the font height to a line position to get a top of line index. This caused the previous line also to get refreshed, sometimes into an incorrect place. - bas'

Description: '
In the expression':'
Switch the two PROGN clauses. In one direction, one gets SETEDITMENUYCDS (i.e. a Y showing thru the SETEDITMENU).  This is because the WAIT.FOR.TTY is repainted during the SETEDITMENU adjustment, i.e., before it is moved.'

If you have a list whose elements are ((A B C) (A B C D)) and you select (A B C) first and then (A B C D) and then issue the Switch command, the display shows an extra D outside of the (A B C) list.  In general, any white space in the (A B C) list for which the (A B C D) list contains an element will not be properly erased.  If you have the lists ((A B C) (DE FG HI)) and you select the first element, then  the second, and then issue Switch, the display looks like (AEBFC))I instead of (A B C)).'
