Tested with 2014.02.14 beta, and it is a big improvement.  Again, sorry
it took so long to test.

If I use hoffset=3pt, it seems that some underbraces get 3-pt borders
but others don't.  For example,

\setupmathstackers[vfenced][hoffset=3pt]

\starttext

\placeformula\startformula
\underbrace{15\,\tf cm}_{L}
\times
\underbrace{15}_{L}
\stopformula

\stoptext

The second underbrace has the 3-pt borders, but the first one looks more
like a 0-pt border (though hoffset=0pt makes it have a negative border).

Is it due to quantization, in that the extensibles grow in fixed-size
units?
