Subject: In the hex dump, generate the offset at the beginning of each line in
 common code, rather than in print-format-specific code, and have
 "print_hex_data_common()" put out the blank line before the dump itself
 rather than relying on the print-format-specific "start printing the hex
 dump" code to do it.
