Subject: [PATCH] Emit 'cursor:moved' event to update cursor position in status
 bar

Emitting the event *before* update, rather than after. This is because
we read from the DOM after update to measure new characters, which
forces layout, so emitting the event after measuring forces another
layout when the position is updated.
