Sorely missing from vanilla Dired, indeed.

But it's been a feature of Dired+ since at least 1999, and probably several
years before that.  And I've offered that and all other features of Dired+ to
Emacs Dev multiple times.  Still sorely missing, though.

1. `S-mouse-1' marks all of the files in the region (no need for it to be
active).

This is like Windows Explorer: click a file, S-click another file, to mark them
both and all between them.  And `C-mouse-1' marks/unmarks the clicked file, also
as in Windows Explorer.

2. `mouse-3' with an active region brings up a menu which includes items `Mark',
`Unmark', `Toggle Marked/Unmarked', and `Flag for Deletion'.

There are of course individual region commands to do each of those things - not
bound to any keys by default.  The mouse is handy enough - drag to select, then
act on the selected files.  Provided you use a mouse. ;-)

Now it's possible, indeed.  1999.
