	* prj.adb (Compute_All_Imported_Projects): Use new
	For_Project_And_Aggregated_Context to ensure proper context is
	used for encapsulated aggregate libraries.
	* prj-proc.adb (Recursive_Process): Call
	Process_Aggregated_Projects earlier to ensure that all dependent
	projects are set with the proper encapsulated status.

	* s-os_lib.adb (Normalize_Arguments): Properly escape last \ in null
	terminated string.
