When a single argument was a non-commit, the error message used to be:
fatal: BUG: expected exactly one commit from walk
For multiple arguments, when none of the arguments was a commit, the error was:
fatal: empty commit set passed
Finally, when some of the arguments were non-commits, we ignored those
arguments. Instead, now make sure all arguments are commits, and for
the first non-commit, error out with:
fatal: <name>: Can't cherry-pick a <type>

Sure, that makes sense to me.
