Right, no worries!

Oh, right.  I suppose that can be surprising.  Would you like to
resubmit a documentation update?

I wonder if we could use the flunking new 'this-record', and refer to
the SCRIPT-FILE directly in the default parameter list.  But that's
probably overkill for this instance.  :-)

Not sure what/if there are line length limits on guix.texi, but 95
characters should be okay for one-off instances like these.  I suppose
we could escape a line break if it breaks someones workflow.
