I tried booting the kernel/userland from middle of August, and
it had the same problem, so it's definitely not related to this commit.
Sorry about the confusion.

I forgot mentioning that I use /bin/sh as my login shell (and login shell for
root, too) and usually use `exec bash' after that. When I did the reboot,
bash was the only shell process that was to write out the history.
