Route matches empty strings

[dzhus]

route function successfully assigns a handler even if some of variable captures resulted in empty string. This may be displeasing in certain setups.

With routing table set as follows:

routes = [ (":model", method GET emptyForm)
         , (":model/model", method GET metamodel)

         , (":model", method POST create)
         , (":model/:id", method GET read')
         , (":model/:id", method DELETE delete)
         ]

requesting /test/ gets handled by read', not emptyForm, with id parameter set to empty.
