Display bug with tabs and horizontal scrolling

There is a display bug when a TAB is only partially displayed at the left
edge.  To reproduce enable truncate-lines, type some TABs until the window
is scrolled due to automatic horizontal scrolling, then type some normal
characters.  Reposition the display by typing C-a C-e.  If you now type
DEL you will see that more than one character is erased from display,
depending on how much of the first visible TAB character is actually
visible.  This problem is only reproducable with X, not with tty output.

Andreas.
