Comment 7 for bug 1973622

This was fixed upstream in April 2021: https://gerrit.googlesource.com/git-repo/+/0888a083ec6a23a75d3e681f08ef242acd862573
Versions 2.14 and later do not reference the formatter module anywhere, and neither do the source downloads for this package, as far as I can tell.

My best guess is that something pulls in a years-old version of this tool, but I have no idea what, why, or from where.
