There is a subtle difference, though, between break and other commands.
Because breakpoints re-set, the trigger set must be captured and
re-evaluated at re-set.
I think it is all ok though. It is slightly weird but I think we can
explain it adequately to users.

Sounds very good to me.
I think this is going to interact with my ambiguous breakpoint /
linespec changes. At various points in the new code, linespec iterates
over program spaces; this should be filtered according to the trigger
set. I am wondering whether you are basing your work on this patch set,
and if not, how we can best manage the changes. I would rather not be
in a race to finish, but instead talk about how we can best cooperate.
