This commit was actually sitting in my local repo for 18 months --- I had forgotten about it.

In the last 18 months, I've switched out my primary drive for a new one (with bigger capacity) and had to reinstall Windows (and Ubuntu on my old drive). Any local changes I had (including corrupt indexes) would have been wiped out.

I'm pretty good at cleaning up branches (on the remote) that have been merged, so feel free to push any local WIP branches in the future.

In another project, I was re-basing a feature branch for almost 2 years until I found/fixed the bug preventing the PR.
