	* tree.tcl [Bug 3106208]: Followup. Moved the fixed code of the
	last entry I did (2010-11-09) into a new command Tree::MergeFlag
	and call this from both Tree::itemconfigure and Tree::insert.
	Missing the place in Tree::insert caused another problem, found by
	Dustin Littau.

	* tree.tcl (Tree::itemconfigure): Fix intermingling of node names
	and flag values which can cause an lsearch to fail, by mistaking a
	flag value as the node searched for, and then treating a node name
