Ticket #1998 (EditColumnMark can't go up through newline)

fixed trouble with vertical selection

more detail description:

In block selection mode (shift-F3) it's impossible to go beyond empty line with
up or left arrow (i.e. in top direction).
In general: it's impossible to pass any line shorter than finishing column,
until left arrow is pressed at column 0 (which won't work on empty line), e.g.

xxxCxxx
yyyyy
zzzzzDz

- put cursor in C position,
- press shift-F3,
- go to D position,
- press up arrow twice,
- press left arrow - you're unlocked now and free to go up.
