	* lib-xref-spark_specific.adb
	(Enclosing_Subprogram_Or_Library_Package): detect library-level
	subprograms and handle entries as subprograms, i.e. now both
	library-level subprograms and entry bodies act as enclosing
	scopes.
	(Traverse_Declarations_Or_Statements): process entry bodies just
	like subprogram bodies.
	* lib-xref.ads (Enclosing_Subprogram_Or_Library_Package): comment
	simplified while keeping its the meaning and minor typo fixed
	("of" -> "or").
	* spark_xrefs.ads (Xref Section): fix in description of the ALI
	line for subprogram calls; such lines start with captial "F"
	followed by a space.

	* sem_ch8.adb (Find_Direct_Name): A parameter association is
	a legal context for applying an implicit dereference.
	(Analyze_Expanded_Name): Minor code cleanup.
