+Suppose a remote repository contains a branch named "foo", and you fetch from it.  Then, someone renames that branch to "foo/bar".  The next time you fetch from that repository, you will get an error because the obsolete branch "foo" is blocking the branch "foo/bar" from being created (due to the way git stores refs for branches).  Pruning gets around the problem.  It doesn't really add much overhead to the fetch, and in fact it can *save* overhead since obsolete branches do consume resources (any commits they point to cannot be garbage collected).  --[[blipvert]]
