Daniel usually insists on test cases and I usually insist on
documentation for any user-visible changes.

The reason for those requirements is that if the patch submitter
doesn't do it, someone else, usually Daniel and myself, need to do
that for them.  Both of us are busy people, so asking us to cover for
others runs a risk that new features will remain untested and
undocumented.

Here's a real-life example: Last time I checked (a few months ago),
there were dozens of undocumented commands, which forced me to spend
several days documenting them (since I don't use many of them, I
needed to reverse-engineer the code to understand what they do and
when they are useful).  After that, I've sworn never again to allow
this to happen.
