New description:

 The SVN operation uses svn update, and deletes its working copy if the
 branch changes.  However, Subversion is able to move between branches much
 more efficiently using 'svn switch'.

 Attached is a lightly tested patch that uses 'svn switch'.  It will always
 work for the 'copy' mode; other modes are less tested.  An 'svn switch' of
 a working copy containing unversioned files can in some cases fail; that
 is not handled in this patch.

Comment (by dustin):

 Is the update failure because 'svn' returns a zero (successful) exit
 status in that case?

 Regarding oldsource - you're right.  When I said "yes" I should have said
 "no" :/
