Yeah, perhaps.  tokenize_file() has pushed the return-parallel-lists
notion to the limit of sanity already.  It would make more sense to
change it to return a single list containing one struct per line,
which would include the token list, raw line text, and line number.

It might make sense to proceed by writing a separate patch that just
refactors the existing code to have an API like that, and then revise
this patch to add an error message field to the per-line struct.  Or
maybe that's just extra work, not sure.
