Ah, that was me, to allow comma-delimited lists of parameters to be sent
to the SET handling code. In previous versions, multi-parameter
arguments had to be enclosed in quotes. For most of the SET variables,
lists aren't indicated, but I wanted to use the list for all cases to
minimize the special cases downstream.
If this should be done differently I'm happy for suggestions...
