Emi,

Thanks for sending this patch.

How about replace all the code that's inside

  if (bpt->type == bp_watchpoint || 
      bpt->type == bp_hardware_watchpoint ||
      bpt->type == bp_read_watchpoint ||
      bpt->type == bp_access_watchpoint)
    {
      [re-create a lot of stuff for our watchpoint...]

by a call to update_watchpoint (bpt, 1)?  Would that work in your case? 

When I looked at what update_watchpoint does and what do_enable_breakpoint
does for watchpoints, it seemed to me that do_enable_breakpoint was trying
to do the same, except that it was missing a few pieces. Does anybody see
a reason for the code almost-duplication here?
