Good point.  Though hopefully this particular use case (finding new
package updates) is well served by ‘guix pull --news’, no?

It’s not entirely clear to me what a ‘guix git log’ command would do in
fact: show the log for the ‘guix’ channel?  For all channels (how?)?
For the specified channel?  For what commit range?

Tagging commits is tricky because users only have a *cached* checkout.
So if we want persistent tags, we’ll have to develop a separate
mechanism.  Could be useful, though perhaps redundant with the
(unimplemented) idea of tagging generation?

In the short term, we don’t need to solve all these problems: we can
also go for ‘git-authenticate’ and rename it once we have these other
