CodingGuidelines and SubmittingPatches are IMHO a little bit hidden in ./Documentation
and with respect to their content should be better placed in ./Documentation/technical.
I don't think SubmittingPatches and CodingGuidelines belong to
Documentation/technical; that location is mostly reserved for API
documentation. Also, being prominent documents, they're probably
linked to by many places on the internet. I wouldn't want to
unnecessarily break those links.
