new imports are not associated with the series one started at

[Robert Collins]

e.g. starting at a series with no branch, there is text saying to link a
branch, or ask for an import where is says "If the code is in git, CVS
or Subversion you can request that the branch be imported to Bazaar."

After following that link and creating an import, the new branch is not
associated with the series that one started at. It is not clear to users
that it won't be associated, and would be nicer if it auto associated
(e.g. via a hidden form field or something).
