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.
