I was afraid that setting the default non-empty would cause objections.

I have reworded that part.

I have attached a new version that leaves the parameter empty by default.

The patch is not motivated by my personal dislike of certain error messages.
A well-written application would not need that parameter at all.
The motivation for me is based on my dealing with customers' log files,
which are often full of messages that are only distracting from serious
problems and fill up the disk.

But you are probably right that it would be hard to find a default setting
that nobody has quibbles with, and the default can always be changed with
a future patch.
