Huh, I lost track, but I never meant to say "the functions should
return silently with error code when err == NULL".  I said that it
is another plausible expectation, hence justifies the comment to
clarify, but wished that there were no need to clarify in the first
place.

If everybody required err != NULL, there would be no need to clarify
which functions require err != NULL.  If everybody accepted err ==
NULL as a more efficient way to do "--quiet", that is another way to
remove the need to clarify.

Either way is fine and I did not "propose" anything ;-).

I think this matches more-or-less what I've locally tweaked after
following the discussion between you and Jonathan.  Thanks.
