Fixing the prefix in the tarball makes sense to me, however some of the
other changes do not. The release process is supposed to proceed from a signed
tag, which means that if the version for that signed tag is wrong, then
something prior in the process has gone wrong.
In general having export.sh modify the contents of the exported source tree
in any way is dangerous since it will lead to divergence between the contents
of the git tag for a given release and the contents of the exported tarballs
for that release, and that is obviously really bad.
