git-cherry-pick and git-commit --amend in version 1.7.6.4

Hi,

still with version 1.7.6.4, when I do a cherry-pick, that succeeded, I cannot do a commit --amend after:

# git cherry-pick 3f78d1f210ff89af77f042ab7f4a8fee39feb1c9
[dev 1a04a23] drivers/net/usb/asix.c: Fix unaligned accesses
  1 files changed, 33 insertions(+), 1 deletions(-)
# echo $?
0
# git commit --amend
fatal: You are in the middle of a cherry-pick -- cannot amend.
#

The same operations (with the same patch), with version 1.7.3.4 is ok.

Regards, Nicolas
