First, you should realize that even though the notes are "conceptually" tied 
to a commit (or any other type of Git object), the note objects are 
_technically_ independent from the annotated objects. In fact, the note 
objects live on a separate ref with a wholly separate history. In other 
words, it does not make sense to define the note in the very same 'commit' 
command that you're trying to annotate. Instead, you should organize it 
something like this:


commit refs/heads/master
mark :1
committer user <user@example.com> GMT+0000
data length_of_my_comment
my_comment
M 644 inline my_file
data length_of_my_file
my_file_content

commit refs/notes/commits
committer user <user@example.com> GMT+0000
data length_of_dummy_comment
dummy_comment
N inline :1
data my_note_length
my_note_content


(Obviously, you can add notes for several commits in a single "commit 
refs/notes/commits" command).


Hope this helps,
