Allow for MAINTAINERS to become a directory and if it is,
read all the files in the directory for maintained sections.
Also look for all files named MAINTAINERS in all subdirectories
excluding the .git directory.
This adds ~.3 seconds of CPU on an Intel i5-6200 with an SSD.
Miscellanea:
o Create a read_maintainer_file subroutine from the existing code
o Test only the existence of MAINTAINERS, not whether it's a file
