Very nice. Wonder how did this get in, we've done a typo cleanup not that long ago...

[bbatsov]

@psfinaki I noticed one type when I was reading something in the code and afterwards I thought it might be a good idea to run codespell on all the code. Those are not all of the typos it discovered, but I wanted to check if there's interest in such small fixes to begin with.
