One dark and stormy night I turned away an old woman at my doors, 
and ever since I have been cursed to include at least one stupid 
typo in each patch I send.  True story.

Thanks for testing.  Fixed but it should not affect running guix 
lint.

Hmm.  I bet ‘rm -rf ~/.cache/guix/http’ will make this go 
conveniently away, just like lady stormypants.

This is a stale cache file lacking the newly added ‘severity’ 
field:

(v "CVE-2021-0212" "MEDIUM" (("contrail_networking" ...

I bumped the format version to 2 in (guix cve) to signal this 
incompatible change, but it appears this field may exist merely as 
a friendly reminder to actually add version handling some day...?

I guess today is that day.

Bah,
