[PATCH cygport] Fix handling of python{2,3} atoms in DEPEND

[Jon Turney]

python{2,3} atoms are not deparenthesized correctly, as that function
assumes the atom type consists of lowercase alphabetic characters only.

Probably also need to allow uppercase alphabetic characters as well, to
allow R atoms to work...
