bundle: add test for Issue1704 Original version by Greg Ward.

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.

convert: reenable SVN support after license issue solved

patchbomb: normalize date format in generated mboxes mbox format should use time.asctime(). Unfortunately, this function writes 2-characters day of week on Windows while unix one writes a single character. Normalize to Windows version since the other one can hardly be written with strftime().
