Ok, thanks.  Assuming that markers intelligently follow edits, this
could be even more useful than saving the text the user entered
(obviously this wasn't possible to implement in Insight, as edits took
place outside the application).  Whether it actually is, in practice,
I'll be interested to find out.

It seems like there must also be an event indicating that a new
breakpoint has been created.  The user might create a breakpoint using
"b main" in the console window, and this information must propagate to
the UI.

I do wonder whether anything other than simply saving the user-entered
text will be useful for "b *addr" breakpoints.  This feature is not
widely used by people debugging natively (in my experience anyway), so
maybe it doesn't matter yet.

Ok.  But it is less useful to let the user set a breakpoint where it
doesn't make sense to set one, for instance in the middle of a comment
(or "#if 0" code).  It seems to me that it would be more friendly,
UI-wise, to present this information to the user when it is available.

What would such a view be used for?
I don't recall ever looking at this information while debugging.


Also, I think it would be safe to remove catchpoints from the initial
set of interfaces.  I think catchpoints, if they work at all in gdb,
work only on HP-UX.
