Re: -I switch to ls and dired.

[Richard Stallman]

    Dired seems to _systematically_ make two assumptions:

    1.  No options take arguments.  Equivalently (or so I believe), -I is
        not used.

    2.  No long options are used.

    We can either just document those two assumptions or try to
    systematically get rid of them.

I'd say document them.  It isn't worth a lot of work to get rid of
them.
