Newline wrongly included when selecting past the start of a line

[GoogleCodeExporter]

During text selection, if the mouse is dragged to the left of the window,
the newline preceding the line the mouse is on is included in the selection.

The same issue occurs when starting a selection to the left edge of the
first character on a line, which is quite easy to do when the window is
maximised.

Fixed in r635 on 0.5 branch, albeit at the cost of including the first 
character when
selecting downwards and dragging the mouse to the left of the window.

The underlying issue is that the mouse positioning ranges from 0 to 79 for an
80-column window, when it should really be 0 to 80 to distinguish "before the 
first"
and "after the last" character. Fixing that would require some redesign of all 
the
selection-related code, so leaving that for the moment.

Improved fix in r636 on 0.5 branch, no longer including the first character on 
a line
when selecting downwards and dragging the mouse to the left of the window.
