It's not obvious that:

 git push # pushes master
 git push --tags # just pushes tags and not master

and that you have to:

 git push origin master --tags

To push both.

You can simple 'git commit --amend' your merge commit and give
it a better subject. The merge commit check is intentionally
a dumb check on whether the subject matches:

 ^.*Merge branch.*of.*(git|ssh):

You couldn't do this for your situation since you had such
commits as ancestors of the tag, but if it's just a single
commit merging things back together to push to master, then
it's easy.
