Subject: checkpatch.pl: REPEATED_WORD: massive false positive in
 MAINTAINERS

Dear Joe, dear Dwaipayan,

while maintaining MAINTAINERS, I noticed that the REPEATED_WORD check, 
which in general is a great addition to checkpatch.pl, generates a massive
number of warnings due to one specific pattern in the MAINTAINERS file:

$ ./scripts/checkpatch.pl --show-types -f MAINTAINERS

results in 625 warnings of the following kind:

WARNING:REPEATED_WORD: Possible repeated word: 'git'
#XYZ: FILE: MAINTAINERS:XYZ:
+T:	git git://...

That pattern above is of course intentional and perfectly fine, so now the 
REPEATED_WORD check should not complain here.

Joe, would you accept a suitable refinement of the REPEATED_WORD check 
that address the issue above?

Dwaipayan, is that another good issue for you to look into and improve?
There are multiple ways to handle it either directly checking for that 
pattern or excluding MAINTAINERS or both or something completely 
different.

Lukas
