"git notes add" is identical to "git notes edit" except that instead of
editing existing notes contents, you can only append to it. This is
useful for quickly adding annotations like e.g.:
git notes add -m "Acked-by: A U Thor <author@xxxxxxxxxxx>"
If there is no existing note to append to, "git notes add" is identical
to "git notes edit" (i.e. it adds a new note).
The patch includes tests verifying correct behaviour of the new subcommand.
