[bug#61052] [PATCH] download: Add url-fetch/xz-file.

[Tobias Geerinckx-Rice]

Hi Hilton,

I agree with Ludo' and also wonder if a generic 
‘url-fetch/compressed-file’ wouldn't be better.  There are closure 
arguments to be made for this xz-only approach.  I don't know if they're 
convincing.  Cluebats welcome.

(I was going to bring up ‘url-fetch/tarbomb’ as an example, but it 
doesn't actually handle anything besides gzip!  Madness.)

…when we have full control over xz's arguments?

Kind regards,
