And I'm pretty sure we concluded there wasn't a reasonable way to do
this... perhaps my example wasn't good enough.  Or perhaps I've
forgotten the trick to it.

(gdb) 
Note: breakpoints 1, 2, 3, 4, 5, 6, 7 and 8 also set at pc 0x439ee0.
Breakpoint 9 at 0x439ee0
(gdb) 
Note: breakpoints 1, 2, 3, 4, 5, 6, 7, 8 and 9 also set at pc 0x439ee0.
Breakpoint 10 at 0x439ee0
(gdb) 
Note: breakpoints 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 also set at pc 0x439ee0.
Breakpoint 11 at 0x439ee0

There can be an arbitrary number of elements.  We build up the list
with ", " and ", and ", along with " (disabled)" and " (thread %d)".

It'd be easy to reduce the possibilities somewhat, by using "%d
(disabled)" and "%d (disabled) (thread %d)" and so forth.  But I'm
stumped what to do about the comma separated list.
