The sh script are harder to maintain for compatible different
xsh environment so convert it to python script
Also incorporate the fixes in
https://patchew.org/QEMU/20200929143654.518157-1-marcandre.lureau@redhat.com/
Using --match=v* instead of --match 'v*' for speed up the git version
And using --match=v\\* to resolve wildcard problem on windows.
Tested under Ubuntu/msys2/mingw.
