* nlmconv.c (main), objcopy.c (copy_file): Print matching formats 

if ambiguous match.
	* nm.c (display_file), size.c (display_bfd): Eliminate gotos.
	Print matching formats if there is an ambiguous match.  Use
	bfd_nonfatal instead of hardcoded error message if nothing matches.

	* arsup.c, ar.c, objdump.c: Use bfd_get_filename instead of
	abfd->filename.

	* nm.c (display_archive): New function, from code in display_file.
	(display_rel_file): Renamed from do_one_rel_file.

	* size.c: Indent.
	(display_archive): New function from code in display_file.
	(display_file): Check bfd_close error return.

	* strings.c (strings_object_file): Check bfd_check_format
	error return.

	* strings.c, objdump.c, size.c: Use bfd_nonfatal instead of bfd_perror.

	* bucomm.c: Delete references to exit_handler.  It wasn't set
	anywhere, and now that we're using the libiberty xmalloc, it
	wouldn't always get called before exiting.
	(list_matching_formats): Function moved from objdump.c.
	* bucomm.h: Declare it.

	* objdump.c (disassemble_data): Move some variable decls closer to
	their use.  Add some comments.  Replace a nested block with a
	return.
