selection: adjust start point when the selection changes direction

Browse source 
Without this, the initial cell will always be selected, regardless of
how the selection is moved to the left or right.

With this patch, the initial cell will only be selected while the
selection is being made in the original direction. Changing direction
of the selection moves the start point to next/previous character.
