Hi,

I get a “Missing { inserted.” error under certain circumstances.
Here is an example:

\starttext
  \blackrule [height=8cm]

  \startpostponing
    \placefigure
      [] {foo}{bar}
  \stoppostponing

  \blackrule [height=15cm]

  \startlines
  a
  b
  \stoplines
\stoptext

I used black rules to insert boxes of a particular height, any
content would do. Funnily enough it works with \placefigure []
{foo}{bar}, but not with

  \placefigure
    [] {foo}{bar}

I have no clue what's wrong here.
