I agree but your commit message didn't say that. It's irrelevant now
Mark has merged the patch, but for anyone looking at the commit message
later, the structure of your commit message implies that the problem
is that {0} doesn't work correctly (probably untrue and certainly not
the actual problem.) and your actual fix relies on precisely the
behaviour that the first line of your commit message implies is broken.

I just like commit messages to be accurate about what the problem was
and why. It's often said that an incorrect comment is worse than not
having the comment at all, and the same could be said for commit
messages,
