	Handle conflicts between options in different groups. (#156808)

	* glib/goption.c (g_option_context_parse): When a long option does not
	match exactly, try to parse it as --group-option.
	(g_option_context_add_group): Warn if a group name conflict occurs.

	* glib/goption.c (print_help): Print out the effective options, ie
	don't print shadowed short options, and for long options print
	--group-option instead of --option if appropriate.
