The FPHSA helper sets both for historical reasons.  We once had a convention
of UPPERCASE names for find module results instead of ExactCase.

Thanks for the patch.  Applied:

 FindGit: Document Git_FOUND, unset internal var
 https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=facfb52c

I followed it up with some documentation formatting improvements:
