It looks like you're right, and strangely enough there's a comment in
sort.c right above the definition of sorted? that has the correct
documentation.
I hope other people will correct me if I'm wrong, but I believe the
ideal thing for you to do now is submit a patch created with git
format-patch. That way you can write a git log entry, and your name
will be associated with the patch. You can see other recent log
entries for the standard guile format.
If you don't want to do this, I can do it for you, but I think it's
nicer if you are listed as the author since you did the work.
Thank you very much for reporting this,
Noah
