RE: A proposal - Dired -`$' and `i'

[Drew Adams]

FWIW, the proposed behavior is the Dired+ behavior.
(http://www.emacswiki.org/cgi-bin/wiki/DiredPlus)

* `i' bounces between a subdir and its line in the parent listing.

* If the parent dir is hidden, then `i' from the subdir opens the
  parent so it can move to the subdir line.

* `$' does hide/show without advancing to the next subdir.

* `M-$' does what vanilla Emacs `$' does: hide/show then advance.

* `C-u $' does what vanilla Emacs `M-$' does: hide/show all.
  (This does not need to be on as quick a toggle key as `$'.
   And it certainly does not need to be on a repeating key such
   as `M-$'.)
