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.
