Just two thing: please add a NEWS entry so people can see
what changed, and please add at least a stub to the documentation
describing that the file exists.

There is a risk that people will confuse themselves, but I think it's
still useful to have them to accomodate personal practices.

Well, I think we would want that list to be more conservative than what
we have at the moment, both to avoid surprising people and to help with
performance.

So I'll give a +1, the patch looks good as written.  If other people
have concerns about adding the feature we can talk about it some more
but I think it's basically reasonable.
