Long Commit Messages

This is a experimental repo to see what would happen if the commit messages are exceptionally long.

It is my understanding that Git internally uses size_t for the commit messages, which means the maximum length is platform-dependent.

It would be interesting to see what would happen when the length exceeds ~(size_t)0, or 4294967295 bytes in 32-bit platforms. But my guess is that before we reach that length, many things would have already stopped working.
