Gbp-Pq: Topic mutt-patched
Patch for sidebar iteration functionality

sidebar-new will move the selected folder to the next with new messages.
If the end is reached, it will start at the top.

Useful macro would be:

	macro index,pager <esc>a <sidebar-new><sidebar-open>
Fix in sidebar-next functionality

The first item in sidebar was always selected, even if there were no new
messages. Now the sidebar-new function works as it should.
