... but this is bogus. ":0:" would be the zero-length atom.

I'm proposing a very simple change here. There are already implicit
atoms and explicit (counted) atoms. Right now implicit atoms start a
letter and explicit atoms start with a number. What I'm proposing is:

  Phase 1: Implicit atoms start with a letter
           Explicit atoms start with a colon
           Atoms starting with a number are treated as explicit atoms
            for backward compatibility, when reading

  Phase 2: Implicit atoms start with a letter or number
           Explicit atoms start with a colon
