[Message part 2 (message/rfc822, inline)]

Subject: 30.0.91; Don't hard-couple
 `dired-hide-details-hide-absolute-location' with `dired-hide-details-mode'
Date: Tue, 22 Oct 2024 18:34:25 +0000

Starting with Emacs 30 Dired directory header lines apparently show
relative names when `dired-hide-details-mode' is on, if option
`dired-hide-details-hide-absolute-location' is non-nil.

(The only Windows v30 pretest snapshot I found doesn't have this option,
so I'm going only by the description from bug #72272.)

The behavior of being able to show only a relative name is a good one,
but it shouldn't be hard-coupled with `dired-hide-details-mode'.  Users
should be able to choose:

 nil                         Always show absolute name.
                             (This needs to stay the default.) 
 if-dired-hide-details-mode  Show relative name only when
                             `dired-hide-details-mode' is on.
 t                           Always show relative name.
 FUNCTION                    Show relative name only when invoking
                             FUNCTION with no args returns non-nil.

The most important behaviors are for nil, t, and
`if-hiding-detail-columns'.  FUNCTION is a nice-to-have.

(An alternative would be to use t for showing relative name when
`dired-hide-details-mode' is on and `always' for showing relative names
always.  That keeps the current pre-release behavior for t.  I don't
think it's preferable, but it's a possibility.)

AFAIU, this behavior was changed in Emacs 31 to be like you suggest, so
I'm closing this bug.
