TOML supports multi-values, e..g.

ip="10.89.23.2"
ip="10.89.23.3"
ip="10.89.23.4"

and claptrap supports multi-values:

cmd.Add("--ip...", "", "a list of IP addys")

but clapconf doesn't support putting multiple values into a multivar arg. This is because claptrap doesn't support multivar DefaultValues, and clapconf sets the DefaultValue.

This is a "deep" issue requiring changes to the claptrap API
