That "slightly" and "some of" are bothersome.  It's nicer if we can
distribute all files as-is.  The distributed files should
have all the info needed to make the distribution, so that the
whole procedure is self-documenting and automatic.

Yes, and that's the advantage of putting the data version number
into (say) zone.tab.  This would avoid races on extraction and
the other problems that you mentioned.  So perhaps we should do
it that way, even if it's a bit more error-prone because the two
version numbers are in different files.
