I have git 2.33 in cygwin and MSYS2, so git is not old. I'll look at
this again now that the changes have stablised.

My note was more to warn that adding this to emacs-28 may bring
problems.

Looking at this again, Trying "C-x v l" for INSTALL in the repo master
branch gives (rewrapped for clarity):

  fatal: :(literal)c:/emacs/git/emacs/master/nt/INSTALL:
  'c:/emacs/git/emacs/master/nt/INSTALL' is outside repository at
  '/c/emacs/git/emacs/master'

This appears to be due to the translation between win32 and cygwin
(posix) filenames.
