[bug#47670] [PATCH 0/2] Add updater for packages hosted as SourceHut Git repositories

[Xinglu Chen]

This adds support for updating packages hosted as SourceHut Git
repositories.  It looks at the Git tags on the remote (thank you Léo for
pointing this out[1]) to determine the latest release.  It won't be as
reliable as the GitHub updater, but still better than nothing, I
guess.

SourceHut also has support for Mercurial, but I am not familiar with it,
maybe I will look into it in the future. :)

See it in action:

$ ./pre-inst-env guix refresh fennel
gnu/packages/lua.scm:1176:13: fennel would be upgraded from 0.8.1 to 0.9.0

Xinglu Chen (2):
  upstream: Add predicate for Git URLs.
  gnu-maintenance: Add 'sourcehut-git' updater.
