Below's just for the record.  I'm okay with whatever you guys
have decided.  ;-)

IMO, either of these would be better API than a silent ignore.
If you go with error, the client of the API can
retry a non-internal breakpoint after e.g., printing a warning,
say.  As is, if you ever add support for internal watchpoints,
then a script has no way to tell whether such internal breakpoints
are actually supported by the gdb at hand until trying: if the flag
is just ignored, too late, the user has already seen the
breakpoint being created...

IMO, it should the script writers' responsibility to weight that,
but it's also okay to not support it until someone asks for it
(though that someone would be happier if she didn't have to,
obviously :-) ).
