Subject: [PATCH] unindent: ensure that a partial line gets displayed properly
 afterwards

When only the trailing chunk of a line is displayed on the top row of
the screen, and the unindenting of this line leads to a reduction in
the number of chunks, then the starting point of the viewport needs
to be re-evaluated.  For simplicity, do this always when something is
unindented.

This fixes https://savannah.gnu.org/bugs/?56102.

Bug existed since around version 2.9.2.
