I've uploaded a fix for pqm submit into its shared branch.

I added creation of an explicit message Option to commit -- I was
trying to make sure they all had meaningful help.  Having the options
globally declared makes it a bit hard to do that -- what is the
message for?

I hadn't realized how many plugins were depending on referring to the
global options by name, which is why I suggested putting them back.
