I have applied all respective changes in the master branch which look
obvious to me. There are still ~40 occurences of /dev/null in the lisp
directory, but most of them are comments. So I'll close this bug.

If people are interested in fixing the few other places, they could do
now by using the null-device variable or function. In case they don't
know what's better, a new bug report for the given case would do,
instead of keeping *this* bug report open forever.

Best regards, Michael.

There are nearly a hundred places in Emacs lisp sources where
/dev/null is used instead of null-device. Please convert those to use
null-device so that it gets system-independent. (I wonder what to do
with those in Tramp.)
