Yes, MSYS2 should understand C:/Temp. This can be achieved easily by
doing the clone with Git for Windows. A small complication is, though,
that the actual contents of the .git/objects/info/alternates is
constructed from the literal command line arguments. In my test I used
git clone -s C:\Temp\repoorig repoclone
which writes
C:\Temp\repoorig/.git/objects
to the file. The path we see in the output of count-objects -v is
obviously a normalized version. Users will have to say
git clone -s C:/Temp/repoorig repoclone
to get the more widely understood version into the file.
