From testing problems in #458 and #460, there is an odd problem with GHA macos instances
(this might also indicate that the root problem may soon get a fix?)
In detail, it seems that the latest-good git installation is not (?always?) put on the front of the path when your GHA runs,
but instead an older system git runs by default. Which, possibly, does not have a "git version" command ?
So, for now, this hack pushes a magic directory onto the front of PATH to make the tests run.
(N.B. wheels are OK and unaffected. The problem occurs when doing an editable install of the repo)
