bundle: don't send too many changesets (Issue1704)
The fast path in changegroupsubset can send too many csets. This happens
because it uses the parents of all bases as common nodes and then goes
forward from this again. If a base has a parent that has another child,
which is -not- a base, then this other child will nevertheless end up in
the changegroup.
The fix is to not use findmissing(), but use nodesbetween() instead, as
do the slow path and incoming/outgoing.
The change to test-notify.out is correct, because it actually hits this
bug, as can be seen by glog'ing the two repos:
@ 22c88
|\
| o 0a184
| |
o | 0647d
|/
o cb9a9
and
o 0647d
|
@ cb9a9
It used to pull 0647d again, which is unnecessary.
