At the end of the queens cycle we had several libraries that had no
releases at all. In order to create the stable/queens branches we
wanted to go back to the point where the stable/pike branch had been
created and tag again, raising the minor version number. This patch
updates the new-release command to compute those values automatically
when an argument of "procedural" is given.
It also extends the schema for the deliverable file to support a
"comment" field. We can't use regular source comments because there is
no way to tell the formatter to emit them.
