make work 

Hello,

I need to use shell plan start/stop commands but unfortunately these commands are not working as following error is raised : Command plan stop: Incorrect number of parameters

Commit f8c19d7 (ttps://github.com/mffrench/virgo.kernel/commit/f8c19d76ae13dcb1c051ed92eb8eff8f2b575e14) is a resolution which makes work these commands on Virgo 3.6.2  (Note : I used the 3.6.2 tags to patch my own environment )... Could you tell me if you see anything wrong on this commit ? 

Thank you
