[NTG-context] Small issue with \breakhere in math mode

[Otared Kavian]

Hi Hans and Mikael,

I found a small issue in math mode with \breakhere. 
When \breakhere is followed by a brace in the following line, it creates a spurious break line.
It can be fixed easily by the user by adding an empty line or issuing a \relax command, but I wanted to let you know.

Please see the result of the following minimal example:

% begin breakhere-bug.tex
\starttext
Compare
\startformula
\alignhere {\darkred c^2} = a^2 + b^2 \breakhere
{\darkred z^2} = x^2 + y^2.
\stopformula
with
\startformula
\alignhere {\darkred c^2} = a^2 + b^2 \breakhere

{\darkred z^2} = x^2 + y^2.
\stopformula
and with
\startformula
\alignhere {\darkred c^2} = a^2 + b^2 \breakhere\relax
{\darkred z^2} = x^2 + y^2.
\stopformula

\stoptext
% begin breakhere-bug.tex

Best regards: Otared

\breakhere accepts an optional argument which has to be enclosed in 
braces and in your example you just passed the argument.

Hi Wolfgang,

Indeed I overlooked the fact that in « mathcontext-screen.pdf » it is explained that:

\breakhere [...] {…} 
1  left right before after page samepage
2 TEXT

Thanks for your patience with superficial users such as me :-)

Best regards: Otared
