FWIW, I think it's already clear enough, given that the value after
dired-maybe-insert-subdir will be something like:

    (("/home/skangas/wip/emacs/etc/" . #<marker at 3031 in emacs>)
     ("/home/skangas/wip/emacs/" . #<marker at 1 in emacs>))
    
I'm not against trying to make it even clearer though.

Do you have a suggestion for how to rewrite this text without going
over the recommended 67 character limit?

    Association list of subdirectories and their buffer positions.

The best I could come up with is this (exactly 67 characters):

    Alist of subdirectories and the buffer positions of their listings.

Best regards,
