It looks like the problem was not just at that particular line, rather
anywhere that happens to call (erase-current-line …) which in addition
to guix/scripts/substitute.scm are guix/status.scm and guix/progress.scm.

Perhaps every instance of <progress-reporter> under guix/ should be
checking whether or not they are running under a tty?

WDYT?
