As of Emacs 22.1, this is correct. But it may change in the future.

Emacs runs on many different operating systems.

The documentation of this variable is not entirely clear to me.
It does not tell me in which way the files that match this regexp
are handled differently than all other files.

Actually not. I just wondered about the default setting.
In my opinion, temporary-file-directory should be preferred over
"/tmp/" or whatever directly set directory, simply because then it
would work on all operating systems when set correctly in one place.

For which Unix/GNU applications does the default apply?

It could only be an improvement. For typical Unix/GNU systems,
temporary-file-directory is set to "/tmp/" anyway.
