The hard part is not to install MSYS2, is to manage the install action
from Emacs. Ask the user, remember his decision, provide a mechanism in
case he changes his mind, detect and use existing installs, decide where
to install... and more.

That's along the lines of what I described on a previous message,
although I went to the extreme of suggesting to provide Emacs as a
pacman package.

Do you know that a pacman package contains a functional install? That
means that once you have the MSYS2 binary package, by simply
uncompressing it, adding the required dlls to mingw64/bin and zipping
the contents of the mingw64 directory, you have your .zip distribution.

That lacks SSL/SSH and Perl dependencies for the commands that still
depend on it.

After looking at

https://github.com/msys2/MSYS2-packages/blob/master/git/PKGBUILD

I was expecting a more complex procedure.

If something as simple as this works, great. Otherwise, another
possibility is to install MSYS2 git (the POSIX package) and tell the
users to set vc-git-program / magit-git-executable, suppossing that it
works. It is slower than the native port, though.
