[NTG-context] Indention problem after formula

[Tobias Burnus]

Hi all,

how does one get an indention after a formula? The last paragraph shall 
be indented, but it is not. Any idea?

We start with a formula,
\placeformula
\startformula
a^2+b^2=c^2,
\stopformula
\noindent which was found by a Greek; it can also be written as
\placeformula
\startformula
a^2+b^2-c^2 = 0.
\stopformula

\indent Here, a new paragraph shall begin -- indented!
