- Take the note message from the given blob object (for

+ Take the given blob object (for example, another note) as the

$ git notes --ref=built add -C "$blob" HEAD
------------
+(You cannot simply use `git notes --ref=built add -F a.out HEAD`
+because that is not binary-safe.)
Of course, it doesn't make much sense to display non-text-format notes
with 'git log', so if you use such notes, you'll probably need to write
some special-purpose tools to do something useful with them.
