[MERGE] Clean up pull -v

[Aaron Bentley]

Hi all,

This patch cleans up the operations used in pull -v, so that they don't
scale with the size of history, and so they're efficient with branch 6
and later branch formats.  In particular, it uses
repository.get_revisions, and does not use Branch.revision_history.
