--[[
Combine named-and-numbered arguments into a pretty list.
"Named-and-numbered" means foo, foo0, foo_1, foo234: anything that matches foo_?%d+

Arguments:
args[1] = name to search arguments
rest of args = arguments to search
Returns:
Pretty list, in order of argument number.
"foo" comes first, then "foo0", "foo1", ... "fooN"
The argument numbering does not have to be sequential

If number of args that match <= args[_limit] (4 default),
returns text list of the form "A, B, C and D"
otherwise returns collapsible list ({{clist}})

if ord then
values[ord+2] = v --- put value into list at number+2 (to keep "foo" first, even for foo0)
