That was fast.  :-)

Nice!

I’d find it clearer to have a first patch that moves code from cran.scm
to utils.scm, and a second patch containing the ELPA changes.  No big
deal though.

Please double-check that tests/{elpa,cran}.scm still pass, but if they
do, I think you can go ahead and push.

Thank you!
