Luca, All,
On 2014-10-12 12:52 +0200, Luca Ceresoli spake thusly:
> This instruction in the middle of 'import' lines looks very strange.
>
> Also, it was not obvious to me what the 'Agg' backend is.
>
> Both things are actually correct, but it took a while to find out why.
> So clarify with a comment to save someone else's time.
