You can write the find_program() command more succinctly as:

	find_program(SH_EXE sh PATHS "C:/Program Files/Git/bin")

PATHS is is a list of extra directories to search, which are usually hard-coded
guesses[1]. This way we avoid an extra check and indentation level.

I found my Visual Studio installation already contains a sh.exe.  I think it
ships with VS by default; I can't even find a way to remove it. It's located
at:

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Git\usr\bin\sh.exe

When I started writing this up I figured that could serve as an additional
fallback. However, if I use that shell I have to add (...)/usr/bin to PATH as
the various scripts need expr and sed among other things. I get the same result
if I search "C:/Program Files/Git/usr/bin", but there is no equivalent
(...)/bin in the Git included with VS for some reason.

For the curious I have attached the patch that ended up working, but I doubt
it's worth including (except the simplified if(NOT...) logic).

Øsse.
