Chapter title in MetaFun manual.

10 Feb 2023

      Dear all,

I copied the code of defining chapter command  from metafun-000.tex, and run it.
But the result is different from that in MetaFun Manual.
There is a big spaces between the number and the title which yields the number cannot be seen.
I commented out several lines which seems to be not-related with chapter title.
And, I changed

	\def\ChapterCommand#1#2% —> \define[2]\ChapterCommand

Would you please test the following code to find out what is wrong?

Thank you for reading.

Best regards,

Dalyoung
