zsh-2.6-beta13-hzoli12's fc looks like fc -2

[Kunihiro Ishiguro <kunihiro@xxxxxxxxxxxxxxxxx>]

Small problem about zsh-2.6-beta13-hzoli12.  Built-in function fc with
no args looks like fc -2.

kunihiro(mokuren)% zsh-2.6-beta13-hzoli12 -f
mokuren% pwd
/usr/home/kunihiro
mokuren% ls
News                    diff                    ptop
RR                      diff~                   rfc1882.txt
mokuren% fc
<run into vi and show 'pwd'. I expect 'ls'>

This doesn't occur with zsh-2.6-beta13. Below code is from zsh-2.6-beta13.
Thanks.
