There is still the anomaly between break_command_really returning int and
gdb_breakpoint returning enum gdb_rc.  Currently it looks like the return value
of break_command_1 is not used, so this could presumably be void.  If the
exception handling is all done in break_command_really perhaps we don't need
the return value of gdb_breakpoint.
