Great!  What about instead of (or along with) "-t cran -t elpa", use a
comma separated list as it is done in "guix lint --checkers=..."?

I think "--foo=one,two" is a general syntax, so it would be good to
support it.  Also this will allow to complete several updaters in a
guix-refresh popup (M-x guix r =t).
