#136 with soft wrapping, arrow keys should follow visual lines

[Joachim Kock]

With soft wrapping turned on:

Currently the behaviour is that navigation keys follow the logical line.
I think the correct behaviour, such as found in word processors, is to
follow the visual line.

For example, in a long logical line spanning three visual lines,
pressing arrow-up near the end takes you to the previous logical line,
where the expeted behaviour is to go ony one visual line up.

[Bernard Desgraupes]

I agree. The core commands previousLine and nextLine have to take soft wrapping into account. Not sure how at the moment...

[Bernard Desgraupes]

This is fixed now. The core commands previousLine and nextLine have been redefined and the bindings thereto have been disabled.
