  * summary:  problems with the Permutation constructor function => [with
              patch; needs review] problems with the
              Permutation constructor function

Comment:

 After this patch:
 {{{
 sage: Permutation([()])
 [1]
 sage: Permutation('()')
 [1]
 }}}
 which agree with PermutationGroupElement:
 {{{
 sage: PermutationGroupElement([()]).list()
 [1]
 sage: PermutationGroupElement('()').list()
 [1]
 }}}
 and:
 {{{
 sage: p = Permutation('(1,2,3)')
 sage: q = Permutation('()')
 sage: gap.Group([p,q])
 Group( [ (1,2,3), () ] )
 sage: gap.Group([p]) == gap.Group([p, q])
 True
 }}}
