Yes.  I'm doing a brute-force folding which could be certainly
improved for readability, but I'm too lazy to do that.

For bookkeeping I track whether we are in a string or in a comment,
handling escaped characters and octal character representations as
unbreakable units.  The maximal line length is set to 78 characters;
if a line gets longer, I break a string with a trailing `\'.  An
overlong comment is simply continued on the next line, and everything
else is broken at the next whitespace.  I don't fold `< ... >' and
`<~ ... ~>', assuming that these constructions don't appear in text
packets of a Type 1 font.
