Did you actually try that, for real?  git.cmd sets PATH to include
git's binaries, which include MSYS DLL.  This means you cannot use in
the same session any commands that might conflict.  E.g., consider
what would happen if you invoke git.cmd from a Makefile, or the other
way around.  I tried that, and got stuck and crashing programs.  No,
thanks.

No, it isn't.  When MSYS DLL is loaded, any other program that is
linked to that DLL will try to use it -- and will fail if it needs an
incompatible version of that DLL.  Therefore, you can't invoke, say,
the MSYS 'make' from the Git Bash shell, or from any Git command.
