I've purposefully added this new error to warn users that their
.guix-channel's introduction forms were erroneous.  Previously, they
were silently being dropped.  The formats in a channels.scm file and in
the .guix-channel file are *not* the same!  Please see "(guix) Declaring
Channel Dependencies" for an example of the format.
