[PATCH 02/11] Improve code comments and whitespace.

[Giuliano Procida <gprocida@google.com>]

These are zero impact changes.

	* include/abg-fwd.h: Correct doc-comment reference to
	enum_type_decl.
	* src/abg-comp-filter.cc: Fix doc-comment syntax.
	* src/abg-comparison.cc (operator<<): In the diff_category
	overload, fix code indentation.
	* src/abg-default-reporter.cc (report): In the
	class_or_union_diff overload, adjust comment to reflect that
	the code is reporting changes between declaration-only and
	defined types, in either direction.
