Agreed.  The -p option is poorly documented.

The intent is that if a subcommand does something with the requested
library then -p includes its parent library (and its parent, etc., all
the way up the chain).

Right now it only applies to the list subcommand, so that "jmod list -p"
shows you all modules in the requested library and all of its parents.

It probably make sense for -p to apply to a few other subcommands, but
I haven't yet thought through the cases.
