grep gives me:

    % grep --color -nH --null -e encoded-string-description **/*.el
    descr-text.el\0350:   (encoded-string-description encoded coding)))))
    descr-text.el\0645:                    (encoded-string-description
    descr-text.el\0655:                           (list 
(encoded-string-description encoded coding)
    international/mule-cmds.el\02900:(defun encoded-string-description (str 
coding-system)
    simple.el\01481:                            (encoded-string-description 
encoded coding)))

and according to my quick investigation, all callers pass a string
that's coming straight from encode-coding-string or encode-coding-char,
so the argument should *always* be unibyte, AFAICT.

Hence according to my reading of the code, this call to
string-as-unibyte will always just return its argument unchanged.
