+	+ modify treatment of "n" parameter for waddnstr, waddnwstr, and
+	  wins_nwstr to return OK when "n" is zero, for consistency with other
+	  implementations (report by Benjamin Barenblat, cf: 20231118).

 20250216
 	+ add limit-checks in alloc_entry.c and alloc_ttype.c to avoid indexing
 	  errors when using infocmp to compare all capabilities when processing
