In toplevel form:
gnus/gnus-start.el:2846:1:Warning: Unused lexical variable `print-readably'

print-readably seem to be a XEmacs option. We have this, for example:

emacs-lisp/edebug.el
3711:(defvar print-readably) ; defined by lemacs
3720:   (print-readably nil)) ; lemacs uses this.

but as we've had some XEmacs-code cleanup, perhaps it's best just remove
the reference from gnus-start.el
