Think that this now does title substitution correctly in all cases..or
at least won't cause failures:
- Use format string chopping to do multiple substitutions since I'm not
smart enoug to get \G to work the way I want.
- deal with a nasty edge case.. where the substitution string was trimeed
in the middle of a LaTeX escaped character sequence (e.g. after \ in \%).
