	* prj-part.adb (Pre_Parse_Context_Clause): Call Set_Is_Not_Last_In_List
	when the project file in a with clause is not the last one, that is the
	project file name is followed by a comma.
	* prj-pp.adb: (First_With_In_List): New Boolean global variable
	(Print): Issue list of project files separated by commas in with clauses
	according to the values returned by Is_Not_Last_In_List.
	* prj-tree.ads, prj-tree.adb: (Is_Not_Last_In_List): New function
	(Set_Is_Not_Last_In_List): New procedure
