Your explanation makes sense, and what you're proposing here seems like
a very reasonable path forward. I can't think of anything that would
cause it not to work as expected.

I'm not a huge fan of adding a 'reinit' parameter to a function that
itself begins with the word 'initialize' (why wouldn't you call
'reinitialize_repository_version()' instead?), but seeing as there are
only a couple of callers, maybe it is OK.

Alternatively, I certainly wouldn't complain if you did introduce a new
function and updated the call-site that passes reinit as 1.

This test looks very reasonable, and certainly demonstrates the bug and
fix. Thanks.

With or without my nitpick:
