[BUG] "git commit" after "cherry-pick -n" conflict clobbers .git/COMMIT_EDITMSG

(only tested with 1.7.10.x for now)

~/softs/linux$ echo foo > .git/COMMIT_EDITMSG
~/softs/linux$ git cherry-pick -n b55f3d92cd
error: could not apply b55f3d9... Linux 2.6.32.26
hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
~/softs/linux$ cat .git/COMMIT_EDITMSG
foo

So far, so good.  But then "git commit" brings me the message from the
cherry-picked commit plus the list of conflicted files, and I can verify that
it is now the contents of .git/COMMIT_EDITMSG.

Surely the fact I passed "-n" should prevent cloberring the message, even in the
event of a conflict.  I suppose that would imply not creating .git/MERGE_MSG in that
case, but just removing it still causes .git/COMMIT_EDITMSG to be clobbered, this
time with nothing but the "git status"-derived comments.
