I noticed it as I experienced the first problems (offloading would
sometimes fail while sending files) and fixed it:

  https://git.savannah.gnu.org/cgit/guix.git/commit/?id=de83660dd386b73957fe4ad2dc08ce5b8e1f0e7f

I also add to re-update the ‘guix’ package.

So I wanted to give a heads-up and apologize.  It got me thinking; this
patch hadn’t gone through guix-patches, which could have prevented this,
maybe.
