Proposed patch

Hi Tom,

  Something like this patch ?

  With it applied the output looks like this:

  [...]
 <0><b>: Abbrev Number: 2 (DW_TAG_partial_unit)
    <c>   DW_AT_stmt_list   : (sec_offset) 0x0
    <10>   DW_AT_comp_dir    : (strp) (offset: 0x4a2146):
/usr/src/debug/gcc-10.2.1-6.fc32.x86_64/obj-x86_64-redhat-linux/x86_64-r
edhat-linux/libgcc
 <1><14>: Abbrev Number: 111 (DW_TAG_base_type)
    <15>   DW_AT_byte_size   : (data1) 4
    <16>   DW_AT_encoding    : (data1) 5        (signed)
   [...]

   There is one caveat with this patch: the form name is only displayed when
--wide is enabled.  This meant that I did not have to fix up all the binutils
tests that run regexps over readelf's output, and it seemed to me to be a
reasonable compromise.

Cheers
  Nick
