Side note: this is more important if you know of a merge issue that
doesn't cause a conflict, and that I won't see in my simple build
tests.

For example, in this case, the merge issue doesn't cause a conflict
(because it's a totally new user of bio_for_each_segment_all() and the
syntax changed in another branch), but I see it trivially when I do a
test build, since the compiler spews out lots of warnings, and so I
can trivially fix it up (and you _mentioning_ the issue gives me the
heads up that you knew about it and what it's all about).

But if it's other architectures, or only happens under special config
options etc, I might not have seen the merge issue at all. And then
it's really good if the maintainer talks about it and shows that yes,
the maintainer knows what he's doing.

Now I'm in the situation where I have actually done the merge the way
I *like* doing them, and without your superfluous merge commit. But if
I use my merge, I'll lose the signature from your tag, because you
signed *your* merge that I didn't actually want to use at all.

See? Your "helpful" merge actually caused me extra work, and made me
have to pick one of two *worse* situations than if you had just tagged
your own development tree. Either my tree has a extra pointless merge
commit, or my tree lacks your signature on your work.

I'll just undo my pull, and delay it all in the hope that you'll just
send me a new signed tag of the non-merged state.
