While

    (add-hook 'before-save-hook #'delete-trailing-whitespace nil t)

is simple enough to put into one's init file, it's a bit rough around
the edges (e.g. for read-only buffers, or interaction with
editorconfig).  So I suggest we add a simple
`delete-trailing-whitespace-mode` minor mode.

Comments?  Objections?
