fc -lr broken in current git?

[Hauke Petersen <hkptrsn@xxxxxxxxxxxxxx>]

fc -lr seems to be problematic in current git:

    % zsh -f
    % fc -lr
        1  fc -lr
    % fc -lr
        1  fc -lr
    % fc -lr
    fc: history events are in wrong order, aborted
    %

Please note that a) it doesn't happen without the -r option, and b) -r 
works fine with the tarred 4.3.17 sources.

This does not seem to be connected to 
<http://www.zsh.org/mla/workers/2012/msg00361.html> as I've tried with 
or without the patch at the time.
