	* glib/gkeyfile.c: Track whether the last key=value pair in a group
	is a blank line and during to_data() only insert a new blank line
	betweens group in its absence. This allows the beautification of the
	GKeyFile and prevents newlines being inserted indefinitely. (#420686)

	* tests/keyfile-test.c (test_reload_idempotency): Test that after a
	single beautification pass, g_key_file_to_data() does not alter its
	input data.
