	* gtk/gtkpathbar.[hc]: Rework the way in which rerooting of the
	path bar is done, implementing the following principles:
	(#137289, patch by Benjamin Otte)

	1. Re-root only if $HOME is an ancestor of the current path.

	2. When re-rooting, make sure the Left arrow appears in the path
	bar, so that you can navigate up from $HOME to /.  In that case,
	make sure the Right arrow doesn't appear if the sub-hierarchy from
	$HOME to the cwd fits in the window.

	3. Make sure that hitting Alt-Up takes you always one folder up,
	even when the path bar is re-rooted.
