	* addr2line.c (unwind_inlines): New flag for 'i' option.
	(usage): Document '-i' option.
	(long_options): Recognize '--inlines'.
	(translate_addresses): Loop, calling bfd_find_inliner_info as
	necessary and printing multiple output lines.
	(main): Handle 'i' option.
	* doc/binutils.texi (addr2line): Document '-i' option.
	* NEWS: Mention new addr2line '-i' option.
