Ah, this is the hunk that causes t6300 to fail. You accidentally removed
the negation when converting the "message" flag over.
This was much easier to find by splitting the refactoring (where the bug
is) away from the new feature (which is where I assumed the bug was).
Here's the first half of the "split". You can rebase your original patch
on top to get the second half.
I also looked at factoring out the "which cleanup mode to select" logic
from builtin/commit.c, but it turned out to just make things harder to
follow.

Subject: [PATCH] tag: refactor passing tag creation options
Rather than continually adding parameters to the create_tag
function, we can put all of the flags in a struct.

Actually, I'm not sure this really buys us much as a refactoring. It
saves a parameter in the function, but it's not like we end up passing
all those parameters to sub-functions, where something like this would
increase readability. I'm fine with this, but I'd also be fine with just
dropping this half and passing the cleanup_mode parameter directly.
