The docstring isn't completely accurate for the current state
of the world. But it does describe the direction future patches
will be taking things.

Move D and E back for the next test

  $ hg bookmark BOOK-D -fqir 3
  $ hg bookmark BOOK-E -fqir 4

Bookmark is usually an indication of a head. For changes that are introduced by
an ancestor of bookmark B, after moving B to B-NEW, the changes are ideally
still introduced by an ancestor of changeset on B-NEW. In the below case,
"BOOK-D", and "BOOK-E" include changes introduced by "C".
