Documentation/notes: document format of notes trees

Separate the specification of the notes format exposed in
git-config.1 from the description of the option; or in other
words, move the explanation for what to expect to find at
refs/notes/commits from git-config.1 to git-notes.1.

+DISCUSSION
+----------
+
+Commit notes are blobs containing extra information about an object
+(usually information to supplement a commit's message).  These blobs
+are taken from notes refs.  A notes ref is usually a branch which
+contains "files" whose paths are the object names for the objects
+they describe, with some directory separators included for performance
+reasons footnote:[Permitted pathnames have the form
+'ab'`/`'cd'`/`'ef'`/`'...'`/`'abcdef...': a sequence of directory
+names of two hexadecimal digits each followed by a filename with the
+rest of the object ID.].

 
 Every notes change creates a new commit at the specified notes ref.
