Comment (by ryandesign):

 While you're looking at this, please also think about the fact that of the
 24 octave module ports that are getting their distfiles from GitHub, only
 5 are using release downloads while the remaining 19 are using the legacy
 download URL. The legacy download URL is deprecated; switch to archive
 URLs, please (`github.tarball_from archive`). This will change checksums,
 so make that change coinciding with a version update, or treat it as a
 stealth update.
