I've committed this new command, turns out `dired-compress' was already
taken:

    (define-key map "c" 'dired-do-compress-to)

Please check if I didn't end up doing something strange. A few points:

1. Is using `cl-find-if' OK in dired.el (I assume this should be fine).

2. There's some autoload regeneration rule that modifies dired.el when
dired-aux.el is modified. Should that autoload be committed together
with a change?

3. Other recipes can be added to `dired-compress-files-alist'. I just
added the two that I'm familiar with. It also needs to be checked if
"zip" typically supports --filesync.

4. I've added NEWS entries, but I forgot how the +++/---/ markers
work. Where is that info? I can document the changes in the manual once
we agree that the change is fine.
