Rolf Eike Beer 745b56f58c Find*.cmake: drop the comments before including FPHSA
No need to explain this over and over again.  While at it, do some other
minor cleanups to whitespace and comments (i.e. delete them).

# The module defines the following variables:
#
# ``GIT_EXECUTABLE``
# Path to Git command-line client.
# ``Git_FOUND``, ``GIT_FOUND``
# True if the Git command-line client was found.
# ``GIT_VERSION_STRING``
# The version of Git found.
#
# Example usage:
#
# .. code-block:: cmake
#
# find_package(Git)
# if(Git_FOUND)
# message("Git found: ${GIT_EXECUTABLE}")
# endif()
# Look for 'git' or 'eg' (easy git)
#
set(git_names git eg)
# Prefer .cmd variants on Windows unless running in a Makefile
# in the MSYS shell.
