Phew! Took some time to realize that \ht\scratchbox-\dimexp is same as
\ht\scracthbox=-\dimexp. Rest of it is same as the earlier definition,
just a bit more easy to understand.

Sorry, here are the correct definitions:
\def\splitfrac#1#2%
{\genfrac{}{}\zeropoint\textstyle%
{\textstyle#1\quad\hfill}%
{\textstyle\hfill\quad\mathstrut#2}}
\def\splitdfrac#1#2%
{\genfrac{}{}\zeropoint\displaystyle%
{#1\quad\hfill}
{\hfill\quad\mathstrut #2}}
In LaTeX if the fourth argument of genfrac can be 0-3 as an
abbreviation for \displaystyle, \textstyle, etc. Since ConTeXt does not
follow this, it resulted in 0 and 1 in the output.

Or probably split core-mat, it is getting a bit too long. How about
disp-mat for all display math related stuff, and core-mat for the
remaining macros in core-mat and m-newmat
