Hi John,
I've updated the docs on the new filter function in doc/reference.txt

and I've implemented the manufacturing of a check function when only a
filter function is specified for a Permission object. This also has a
test. Thanks for that idea!

Let me know if you think we can merge this.

Do you know how to rebase the feature branch to 'default' before
merging? I'm familiar with git but never caught on with mercurial...

Thanks
Ralf
