The presentation in 000403.2 (and the DWARF spec generally) would be simplified
and made more regular if:

    1) The "statement program prologue" were renamed "statement program
       header"

    2) The .debug_aranges, .debug_info, and .debug_pubnames headers
       were described in a manner similar to .debug_line (see 6.2.4/
       page 52). In particular, the header fields would have names.

    These are the proposed names.

      .debug_arange     unit_length
                        version
                        debug_info_length
                        address_size

      .debug_info       unit_length
                        version
                        debug_abbrev_offset
                        address_size

      .debug_line       unit_length (instead of total_length)
                        version                          \
                        prologue_length                   \
                        minimum_instruction_length         \
                        default_is_stmt                     \
                        line_base                            \ unchanged
                        line_range                           /
                        opcode_base                         /
                        standard_opcode_lengths            /
                        include_directories               /
                        file_names                       /

      .debug_pubnames   unit_length
                        version
                        debug_info_offset
                        debug_info_length

Approved: editorial.  Make names consistent.
