fixed IE text selection (needs testing) FS#1808

Ignore-this: c8405fda4cbf2e1fa9d89609e1df666e

This seems to fix the text seelction problem in IE when the selection
starts or ends at a newline.

This was only tested in IE8 so far but should work in IE6 and IE7, too.
Please provide feedback if not.
