command: avoid some direct MPOpts write accesses 

This is working towards a change intended in the future: nothing should
write to the option struct directly, but use functions that raise proper
notifications. Until this is complete it will take a while, and this
commit does not change all cases of direct access, just some simple
ones.

In all of these 3 changes, the actual write access is done by the
generic property-option bridge.
