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.

# basic usage
def test1_simple():
    if os.path.exists('foo'):
        os.remove('foo')
    file = atomictempfile('foo')
    (dir, basename) = os.path.split(file._tempname)
    assert not os.path.isfile('foo')
    assert basename in glob.glob('.foo-*')

    file.write('argh\n')
    file.close()

    assert os.path.isfile('foo')
    assert basename not in glob.glob('.foo-*')
    print 'OK'

    assert basename not in os.listdir('.')
    print 'OK'

# if a programmer screws up and passes bad args to atomictempfile, they
