It's really the same thing as it feeds into the same area of code.
Also, it seems that some of the code already exists as the processing
logic for -P can handing multiple invocations and it's up to the calling
command to allow for it.  If no -P options are specified, then the
global lxcpath config variable is loaded in place of the -P option.  So
they're intimately linked.
