[PATCHv13 21/30] Documentation: Generalize git-notes docs to 'objects' instead of 'commits'

[Johan Herland <johan@herland.net>]

Notes can annotate arbitrary objects (not only commits), but this is not
reflected in the current documentation.

This patch rewrites the git-notes documentation to talk about 'objects'
instead of 'commits'. However, the discussion on commit notes and how
they are displayed by 'git log' is largely preserved.

Finally, I add myself to the Author/Documentation credits, since most of
the lines in the git-notes code and docs are blamed on me.

-git-notes - Add/inspect commit notes

 SYNOPSIS
 --------
 [verse]
-'git notes' (edit [-F <file> | -m <msg>] | show | remove | prune) [commit]
+'git notes' (edit [-F <file> | -m <msg>] | show | remove | prune) [object]
 
 DESCRIPTION
 -----------
-This command allows you to add/remove notes to/from commit messages,
-without changing the commit.  To discern these notes from the message
-stored in the commit object, the notes are indented like the message,
-after an unindented line saying "Notes:".
+This command allows you to add/remove notes to/from objects, without
+changing the objects themselves.
 
-To disable commit notes, you have to set the config variable
-core.notesRef to the empty string.  Alternatively, you can set it
-to a different ref, something like "refs/notes/bugzilla".  This setting
-can be overridden by the environment variable "GIT_NOTES_REF".
+A typical use of notes is to extend a commit message without having
+to change the commit itself. Such commit notes can be shown by `git log`
+along with the original commit message. To discern these notes from the
+message stored in the commit object, the notes are indented like the
+message, after an unindented line saying "Notes:".
