Yep, they don't ship a "git-core" without all this baggage
unfortunately.

Yes, a small install for easy downloads, but with the option for a
bigger one. The small install is still important, though, because it
will also mean a small upgrade from one emacs to the next.

That's true for the msys2 commands but not the mingw64 ones? In the end,
not all of the tools need for Emacs are in mingw64 part of msys2 and
msys2 comes with pacman.

That happens straight away on first launch. I don't know yet, but am
working on it.

Would it be easier to have Emacs allow me to successfully update PATH
during run?
