Hi Jonathan,
[I only saw that you replied to 3/5 with v2 after writing this reply, but
it would apply to v2's 3/5, too]

This breaks on Windows. And it is not immediately obvious how so, so let
me explain:
As you know, on Windows there is no executable flag. There is the .exe
file extension to indicate an executable (and .com and .bat and .cmd are
also handled as executable, at least as executable script).
Now, what happens if you call "abc" in the MSYS2 Bash and there is no
script called "abc" but an executable called "abc.exe" in the PATH? Why,
of course we execute that executable. It has to, because if "abc.exe"
would be renamed into "abc", it would not work any longer.
That is also the reason why that "copy_ssh_wrapper" helper function
automatically appends that .exe file suffix on Windows: it has to.
Every workaround breaks down at some point, and this workaround is no
exception. What should the MSYS2 Bash do if asked to overwrite "abc" and
there is only an "abc.exe"? It actually overwrites "abc.exe" and moves on.
And this is where we are here: the previous test case copied the ssh
wrapper as "uplink". Except on Windows, it is "uplink.exe". And your newly
introduced test case overwrites it. And then it tells Git specifically to
look for "uplink", and Git does *not* append that .exe suffix
automatically as the MSYS2 Bash would do, because git.exe is not intended
to work MSYS2-like.
As a consequence, the test fails. Could you please squash in this, to fix
the test on Windows?
