That's OK, but if the version number reported by the tarball name,
documentation, etc., has only a trailing "+", then it would be odd for
"bison --version" to output something extra, over and above that same
trailing "+".

All other things being equal, it's better for --version output to be
consistent with the rest of the program.  Otherwise we'd have to
document the inconsistency, and explain why it's inconsistent, and I
suspect that whatever explanation we come up with (which I don't fully
understand myself yet) would cause more trouble than it'd cure.
