Hi,

I fixed/extended some experimental code. See attached file. Of course you 
need to move the core file to base and regenerate the format.

If you want autospacing, you need the \epar (this will trigger some line 
width calculations, somethign that needs to take place inside a par).

You can also \moveformula ([-top] but that is the default and onlyh option 
in not grid mode)

\optimizedisplayspacingtrue % needed

test \par \dorecurse{10}{test } \moveformula \startformula test 
\stopformula test \endgraf test
test \par \dorecurse{10}{test } \startformula test \stopformula test 
\endgraf test

\dorecurse{30}{\bpar \dorecurse\recurselevel{test } \epar \startformula 
formula \stopformula}

no guarantees -)
