margins command not displayed entirely

[randomgambit]

Hi Tiesdekok,

I hope you dont mind all these messages ;-)

Here is another bug. The output from the margins command is not displayed in the notebook.

%%stata
sysuse auto, clear
reg price mpg headroom length

gives

as you can see we are missing the means after the at.

Correct output from stata is

Thanks for the bug-report. My code that processed the log-file into the final output that is printed in the Notebook is a little bit wonky, I will look into it and modify it to also properly display output from the Margins command.
