I think scripts/git.orderFile should be part of
"scripts/*" below.

I do not like this because "foo-Makefile-bar"
is not a Makefile, but would match "*Makefile*".


If you do not use wildcard at all, 'Makefile'
will match to the root-dir and sub-directories.


Kconfig
*/Kconfig*
Kbuild
Makefile
*.mak
*.mk
scripts/*


may satisfy your needs mostly.
