I've wondered for a while if we should have something like:

  set tui disassemble-flags ...

where a user can set the flags used by the disassembler.  My main
interest initially was /r, but it might be nice if /m and /s could be
supported too, though I'm not quite sure how that might look or work.

Anyway, if we had something like this then using a disassemble command
could effectively be an alternative path to set the flags. So
something like:

  (gdb) show tui disassemble-flags
  TUI will disassemble using no flags.
  (gdb) disassemble /r 0x.....
  # TUI ASM window updates, and includes opcodes.
  (gdb) show tui disassemble-flags
  TUI will disassemble using flags /r.
  # User doesn't want the opcodes any more, no problem.
  (gdb) set tui disassemble-flags    # <-- passing nothing here to
                                     #  clear the flags
  # TUI updates, but not longer shows opcodes.

Just a thought.

Thanks,
Andrew
