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.

Not completely. The problem is still visible when the window is redrawn
due to an exposure event.

Good catch! That was a completely unrelated bug in expose_area.
