#732: zero matrix dimensions not supported by lil_matrix

     Type:  defect        |      Status:  new   
 Priority:  high          |   Milestone:        
Component:  scipy.sparse  |     Version:        
 Severity:  major         |    Keywords:        
--------------------------+-------------------------------------------------
 The lil_matrix (sparse matrix) type does not support zero matrix
 dimensions. For example,
 lil_matrix(shape=(3,0)) returns an error. This may be considered a defect,
 since numpy itself does support zero dimensions (and so does matlab).
 Workarounds may seem simple, but become a nightmare when a large program
 uses many matrices of a-priori unknown dimensions.
