Must I really understand from your reply that \setupinmargin[x=y] is
not equivalent to \setupinmargin[][x=y]? That is: an absent optional
argument is not really optionally absent?
Your [] is not an absent optional argument at all, it is a given
optional argument (that is empty).
Point taken. But should that has the effect: "ignore what follows in
the second argument?"
It’s a effect how the \setupinmargin command is implemented.
What you tried to do is similar to the effect of the second
\processcommalist command.
\starttext
\processcommalist[foo,bar]\quotation
\processcommalist[]\quotation
\processcommalist[abc,xyz]\quotation
\stoptext
You expect to get
“foo”“bar”
“”
“abc”“xyz”
as output but what you really get is
“foo”“bar”
“abc”“xyz”
The empty argument is ignored and nothing happens.
