Judging by http://www.zsh.org/mla/workers/2001/msg00605.html , the
empty string was never intended as a feature, just a workaround for
not having access to the string. I guess a subsequent change made the
string always be available. Possibly the feature that always keeps the
last command in history until you run another command is newer than
this change and is why it always works now.
