It might not be clear whether Slevin did that, but I certainly did and
reproduced the behaviour he reported on both
OSX and Linux. I didn't expect it to work on OSX (3.2.17) since
.bash_history doesn't seem to have a format that would allow it. The
version I tried on Linux 3.2.25 does have a .bash_history format that
could support it, but it still behaved the same way.
