Hi Chris,

  Right, first of all, I have checked in the patch along with the changelog
entries below.

  Secondly you asked: "What was your rationale for remove *all* coprocessor
instructions?"  The answer is that I did not.  I just restricted the coprocessor
instruction display to those that are guaranteed to be supported by the given
architecture, as determined by the macros in the include/opcode/arm.h file.  If
the user wants to see all the coprocessor instructions they can invoke the
disassembler with the "-marm" switch.

Cheers
  Nick
