This patch series fixes some bugs in generation number v2. They were
discovered while building generation number v3, but that implementation will
be delayed until these fixes are merged.

In particular, Git has been ignoring corrected commit dates since shortly
after they were introduced. This is due to a bug I introduced when trying to
make split commit-graphs safer with mixed generation number versions. I also
noticed an issue with the offset overflows that I only noticed after writing
generation number v3 using a smaller offset size, actually triggering the
bug in the test suite.

Updates in v2
=============

 * Dropped generation v3 patches, saving them for later.
 * Updated a commit message to more clearly describe the problem with the
   old code.
 * Used an || instead of two if statements in test script.

Thanks, -Stolee
