 Replying to [comment:2 hamish]:

 > It would seem that by design (at least in 6.5) if you use a command line
 parameter more than once the parser concatenates them together with ',' as
 the f.sep.:

 Correct; this feature has existed since forever, but isn't widely known.
 It can be useful in conjunction with e.g. xargs, as generating multiple
 options is easier than trying to glue the values together into a single
 option.

 scanning for illegal map names &/or if multiple=NO?

 Try r48205 (7.0).
