(address_base, address_pad_len): New var.
(output_address_fmt_string, address_fmt_buffer, address_pad): Remove.
(flag_pseudo_start): Now int, not long int.
(pseudo_offset): Now off_t, not long int.
(n_specs, n_specs_allocated): Now size_t, not unsigned int.
(format_address, format_address_none, format_address_std,
format_address_label): Now accepts an extra char argument (an extra
char to print if nonzero), and prints instead of returning a string.
All callers changed.
(bytes_per_block): Now size_t, not int.
(format_address_none): Do not even print the extra char argument.
This simplifies the callers.
(format_address_std, format_address_label): Print off_t ourself
instead of trying to use autoconfigured format. This is faster and
more portable.
(format_address_paren): New function.
(dump): Remove unnecessary cast.
(expand_address_fmt): Remove.
(main): Use size_t, off_t, etc. instead of builtin types where this is
advisable. Adjust to above changes. Remove unnecessary cast.
