Make sure ikiwiki generated PO files satisfy the requirements we want check_po to set
One related question: does ikiwiki itself generate PO files that satisfy the new requirements introduced by this branch? I hope so but if not, then we have a problem: every time ikiwiki on our live website updates/creates a PO file we will get test suite failures.
First iteration (#16328 (closed)) will disable checks that are not satisfied by the PO files generated by ikiwiki. And then we can decide which ones of these disabled new checks we really would like to enable, and then we’ll have to fix ikiwiki/po4a before we can do that.
