I think there's room to interpret this convention as consistent with
the new behaviour.  From Guile's perspective, the script filename
appears as an option (as it always has done); non-options are not
passed into whatever code gets run as the value of (cdr
(command-line)).  All the recent change does is say that, for
convenience, you can leave out the "-s".

Agreed, and this is what happens:

address@hidden ~]$ guile test.scm -s switch -- arg
("-s" "switch" "--" "arg")

where test.scm is:

(write (cdr (command-line)))
(newline)
