[CM] CM tutorial example raises out-of-range error on guile/Snd

[Carlos Pita]

A different error is thrown in each case (standalone
guile with and without ice-9 format):

with ice-9 format)

guile> (list-objects #&pulse :end 10)
0. /usr/share/guile/1.6/ice-9/format.scm:123:19: In
procedure substring in expression (substring
format-string 0 ...):
/usr/share/guile/1.6/ice-9/format.scm:123:19: Argument
3 out of range: 2
ABORT: (out-of-range)

without ice-9 format)

guile> (list-objects #&pulse :end 10)
objects.scm:338:24: In procedure simple-format in
expression (format #t "~d. ~s~%" ...):
objects.scm:338:24: FORMAT: Unsupported format option
~d - use (ice-9 format) instead
ABORT: (misc-error)

Carlos
