archive: make it work with svn subrepos (issue3308) - _svncommand() in files() returns a tuple since 0ae98cd2a83f not a string. - _svncommand() in filedata() returns a tuple not a string. - "svn list" returns files but also directories. - "svn list" is not recursive by default. I have no idea what happens to svn:externals possibly embedded in the svn subrepository.
