Aah, excellent.

Can you provide a Makefile rule for that, together with a comment?

Well, these changes are easy to explain!  To assure correct stacking
of brackets, parentheses, and braces which are vertically extensible
and thus built up from elements, symbol.sed assures a unified height
and depth -- eqn uses the \n[rst] and \n[rsb] registers to get this
information (cf. src/preproc/eqn/delim.cpp).  It also adds
mathematical positioning information for the integral sign.

I've just slightly extended the comment in symbol.sed.
