This version incorporates most of Taylor's comments and suggestions. Thanks
especially for the wording suggestions, I struggled with those a lot :)

(I believe) I've responded upthread with my intention for each comment. The
only differences between that and the actual changes are:

 * In Documentation/git-config.txt, I dropped a suggestion to mention that
   "git config --local" is identical to the default behavior when writing
   options because I found it too hard to fit in.

 * In Documentation/config/discovery.txt, I took Taylor's suggestion, but
   didn't mention "discovery" for the same reasons.

 * I decided to leave out the protected config lookup functions. I made some
   POC patches at:

These patches overall looked ok.  I am not very happy to see the
proliferation of namespaces like safe.* and discovery.* that would
not likely to get the second variable, though.
