I can confirm that I did write an initial version of this, which Josh
cleaned up for the mailing list (thanks!). Most, if not all, of the
mistakes are originally mine.

One alternative to this is to trace all of the repository setup process.
E.g. if we traced the data points in t/t1510-repo-setup.sh, like GIT_DIR
and whether the repository is bare, you could reverse-engineer whether
we've hit the "set up a bare repository without GIT_DIR" case, but
that's significantly more complicated. If the goal of this patch is to
make it easy for users, tool developers and sysadmins to see if
"safe.bareRepository=explicit" might be tripped, giving a single,
meaningful event is much easier way to get there.

It would be nice to trace all of the repo setup eventually, anyway, and
I don't think this change precludes that.

Leftover from Gerrit, perhaps?

Unsurprisingly, I don't have comments on the diff, at least not anything
that Junio hasn't already spotted.
