Other than suggesting that you insert a space after the colon in the
subject, I don't have any further comments on this patch. That's
probably not a reason to resend, though.

As general commentary to any potential GSoC students reading this: do
what you can to ease the review process. One way to do so is to supply
commentary below the "---" line (or in the cover letter) explaining
what changed in the present patch compared with the previous attempt.
Bonus points for providing a reference to the previous version of the
submission, like this [1].
