I'm not clear which file actually puts this substitution in substvars; I
tried to track it down but couldn't find it.  Clearly whatever file does
that should provide two variables (Source-Version and Binary-Version are
indeed better names than I was thinking of).  If I found the file, I'd
write and submit a patch.

Right.  Hmm.
