`git commit` relies on the presence of CHERRY_PICK_HEAD to show the correct error message in the case of an empty pick. This fixes a regression introduced by the conversion from shell to C. In the shell version everything was a cherry-pick as far as the sequencer code was concerned so it always wrote CHERRY_PICK_HEAD. The conversion to C forgot to update the code that creates CHERRY_PICK_HEAD. We do not want to create CHERRY_PICK_HEAD for fixup and squash commands as that would prevent `git commit --amend` from running. Note that the error message shown by `git commit` for an empty pick during a rebase is currently wrong as it talks about running `git cherry-pick --skip` rather than `git rebase --skip`. This will be fixed in a future commit which is why the tests are in t3403-rebase-skip.sh. Signed-off-by: Phillip Wood <phillip.wood@dunelm.org.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>
