rewind: make sure merge commits include files from p1 and p2

Otherwise rewinding a merge commit makes it lose all changes.

This fix populates `updates` argument of rewriteutil.rewrite() with parent
changesets. That argument is normally used for folding multiple changesets, but
in this case it's simply used to include files from p1 and p2. Usually,
rewrite() works fine using ctx.files(), but that function can return an empty
list when ctx is a merge commit.

check that the --duplicate option does not create divergence

  $ hg touch --duplicate 10 --hidden
  1 new orphan changesets

check that reviving a changeset with no successor does not show the prompt

  $ hg prune 13
  1 changesets pruned
  $ hg touch 13 --hidden --note "testing with no successor"
  1 new orphan changesets
  $ hg obslog -r 13 --hidden
