test: update test-bundle2-format.t comment Now that bundle2 is used by default for all exchanges, this comment is obviously out of date. Having deep testing of the API and expected behavior of the format and its processing is still valuable, so the comment is updated.

Rebasing
D onto H - simple rebase:
(this also tests that editor is invoked if '--edit' is specified, and that we
can abort or warn for colliding untracked files)

  $ hg clone -q -u . a a1
  $ cd a1

  $ hg tglog

(this also tests that editor is not invoked if '--edit' is not specified, and
that we can ignore for colliding untracked files)

  $ hg clone -q -u . a a2
  $ cd a2
  $ echo collide > D

E onto H - skip of G:

if they have the same contents)

These will fail (using --source):

G onto F - rebase onto an ancestor:

F onto G - rebase onto a descendant:

  $ hg rebase -s 5 -d 6

G onto B - merge revision with both parents not in ancestors of target:

  $ hg rebase -s 6 -d 1
  rebasing 6:eea13746799a "G"
  abort: cannot use revision 6 as base, result would have 3 parents

These will abort gracefully (using --base):

rebase with multiple root.
We rebase E and G on B
We would expect heads are I, F if it was supported

  $ hg clone -q -u . ah ah6

each root have a different common ancestor with the destination and this is a detach
