Thanks for checking. Looking into this, seems like it never worked in 
the Python REPL buffers (or at least hasn't for a long while).

The `company-capf' backend wasn't used, you were simply getting 
completions from `company-dabbrev'.

I've pushed a fix below to the master repo. It should work now.

Sounds odd, but you probably weren't getting the right completions in 
this scenario, too.

The company-mode issue tracker is an okay venue for this kind of 
questions, too.
