[NTG-context] inline-graphics and unwanted line-break

[Peter Schorsch]

Hi, 

I have a small metapost graphic I like to use inline. But the arragement 
behaves a little bit "unpractically". As soon there is no character in front 
of the graphic context will break the line after the graphic - but as soon 
there is a character in front of the graphic, context does not adding a 
linebreak after the graphic.

Does anyone know how to prevent the line-break after the graphic if the 
graphic is the first inline?

Thanks, P.

example-file:

\startuseMPgraphic{zo}
	color schwarz ; schwarz := (.0,.0,.0) ;
 	draw 
(0pt,0pt)--(0pt,8pt)--(5pt,12pt)--(10pt,8pt)--(10pt,0pt)--(0pt,0pt)--cycle 
withcolor schwarz ;
\stopuseMPgraphic

\starttext

\hbox{\useMPgraphic{zo}} test text - why a line-break? How to prevent this?

a \hbox{\useMPgraphic{zo}} test text - this is fine: no line-break!

\stoptext
