Hmm....  For me, mathtext renders your expression as latex does
(except that with latex \hspace needs units and the resulting
\Delta looks a bit less slanted).  The result does appear to
include the product of variables v,e,r,s,u,s,s,o,m, and e.  The
variables are set in a roman font, but are still in math mode.

I can't tell if you're getting or *expecting* different results
from what latex gives.  All I can say is that mathtext seems to
behave correctly (ie, closing emulating latex) for me.  I would've
sworn this was the behavior of recent versions of mathtext, but
perhaps it has not always been this way.

IMHO, I think the decision to closely emulate TeX for math
typesetting was billiant, and that the implementation is amazing.
