Once more, with feeling.
By default now git creates on clone the configuration which essentially says to fetch (get) all "proper" branches the remote has. (By "proper" I mean branches residing under 'refs/heads/'). That is what the wildcard spec above says.
Now when the remote repository dropped some branch (branch was deleted on remote), te corresponding local tracking branch (in 'refs/remotes/origin') does not get deleted.
You can delete _all_ "stale" tracking branches, which means deleting all tracking branches for which corresponding tracked branches were deleted on remote. Or you can delete _one_ specified tracking branch using "git branch -r -d".
Note that you told git to delete tracking branch, not to stop tracking all branches in remote (as in above wildcard regexp), or stop tracking some branch (the configuration earlier version of git created on clone, without wildcard pathspec). So when you ask git to fetch from remote again, it happily re-creates deleted branch. Note also that git *cannot* distinguish (yet) between newly created branch on remote, and branch which tracking branch you have deleted, either by accident or on purpose.
As to documentation: <tongue in cheek> if you cannot distinguish between tracking branch and tracked branch then it is your damn fault ;-PPPP </tongue in cheek>
Analogy: if you delete file in working area (git branch -d -r), and checkout again (git fetch), the file will be resurected.

I'm most interested if "fetch = !refs/heads/branch" or "fetch = -refs/heads/branch" works as a way to specify exclusions from refspec.
P.S. Solution would be to use git-remote or ls-remote and some magic to generate full list of refspecs instead of wildcard refspec.
P.P.S. We used to have similar problem with the introduction of wildcard refspec, namely: which branch from all fetched to merge :-)
