backout: disable --merge with --no-commit (issue4874)
Because "backout --merge" have to make a commit before merging, it doesn't
work with --no-commit. We could change "backout --merge" to make a merge
commit automatically, and --no-commit to bypass a merge commit, but that
change would be undesirable because:
a) it's hard to fix bad merges in general
b) two commits would be created with the same --message
So, this patch simply disables "--merge --no-commit".
