More or less solved, and I feel a little silly at missing it the first time
around. Huzzah for exploratory debugging. For the search engine record and
lurkers:

Use the CommonTokenStream's mark() and
rewind() functions. (Assuming you've already disabled ANTLR's recovery attempts)

Alternately, the index() and get() methods of CommonTokenStream can pull
back the next Token about to be processed, which in turn has information
about it's offset within the stream or original string.
