change environment depth deselects selection

[levon]

From: Daniel Sattler <daniel.sattler@…>

Using Lyx 1.1.6fix4 I could mark several paragraphs and change their
depth multiple times by using the toolbar icon. The paragraphs still got
marked after pressing it.

Using Lyx 1.2.0 this won't work. After each change I've got to mark the
paragraphs again. That's really boring.

613 we have to reset the selection, because the
614 geometry could have changed
615 setCursor(bview, selection.start.par(), selection.start.pos());
616 selection.cursor = cursor;
617 setCursor(bview, selection.end.par(), selection.end.pos());
618 updateCounters(bview);
619 clearSelection();
620 setSelection(bview);
621 setCursor(bview, tmpcursor.par(), tmpcursor.pos());

I don't follow this code ... can we work around it ?

Well, I don't know what the clearSelection() was there for, but
I couldn't reproduce a regression by removing it.
