Nice!  I haven't looked closely, but does this somehow update the code
that computes source URLs using 'string-append'?  If so, that's
impressive :)

In other news, here's another batch of bad source URLs that Hydra
recently failed to fetch:

  mirror://savannah/starfighter/1.7/project-starfighter-1.7-src.tar.gz
  mirror://cpan/authors/id/P/PI/PIJLL/DateTime-Calendar-Julian-0.100.tar.gz
  mirror://cpan/authors/id/A/AD/ADAMK/Object-Signature-1.08.tar.gz
