Not for my version of Latex, which is the one that comes with
tetex-2.0.2-13.  These are actually TeX commands, which Latex
honors.  It makes sense to interpret the first $ in $$ as the end
of text-math mode, rather than the beginning of display-math in
the middle of text-math.  But I agree that this could usefully be
changed.  The point of the present version is to make all the
letters normal rather than slanted.  I guess I favor the slanted
version in the last line, since that seems to be the custom in my
field for $t$.
