Your patch blows up on regular text with underscores, like
samples/render-test.dia.  They and other TeX special characters will
have to be escaped if this is to be usable on common text.  So we face
(again) the decision of whether formulas or text is the most common
output that we should make sure to handle properly, and the other kind
of output will require manual intervention.

Maybe we can for now have it by default escaped and leave the unescaped
version in there as a comment so that replacing that will be easy?
