Just FYI -- it will be a while longer.

I realized today that the treatment of output_format is different with
the patch.  In particular, the old code distinguishes between the
format that is passed in and the global output_format in some places,
but the new code does not.

One way to see this is by setting output-radix.  Before the patch:

  (gdb) set output-radix 8
  (gdb) print enum_constant
  $1 = enum_constant

But after:

  (gdb) set output-radix 8
  (gdb) print enum_constant
  $1 = 01

I'll go back and introduce a second 'format' field in
value_print_options, unless someone has a better idea.

This behavior is not tested for.  So, I'll also add some test cases.

I can send the current patch if you want it for something more
immediate.  Relative to the previous one it has some bug fixes plus a
ChangeLog entry.
