Looks OK to me.

But there is still one weak point (not introduced by your patch). In
`python-shell-send-file', there is the form

(or (expand-file-name
     (or (file-remote-p file-name 'localname)
         file-name))
    temp-file-name)

The intention is obvious: if `file-name' is nil, use `temp-file-name'
instead. But in this case, we would eval (expand-file-name nil), which
raises an error. Could you fix this as well?

I would commit this patch in your name, if this is fixed. Ah, a
ChangeLog entry would be great.
