Please keep ‘match’ instead of ‘cadr’.

Also, the line above should be (cadr (command-line)) instead of (cadr
command-line).

Lastly, there’s a problem when #:auto-login? is #t because
(command-line) returns a 1-element list.  This will be naturally fixed
when the ‘match’ form above is reinstated.

Add a comment below ‘%default-xsessions’, like

  ;; List of monadic values denoting for .desktop files blah blah

> +(define (xsessions-directory sessions)
> +  "Return a directory contains SESSIONS, which should be a list of monadic

s/contains/containing/

Other than that, it looks fine to me.  Could you send an updated
version?

Thanks!
