I'm not sure it matters in the base cases of bzr help and the man page. 
I do think the capitialisation is important though when text is rendered 
in slicker paper documents, e.g. books that have a special "Note" symbol 
in the sidebar in place of Note: as text. In other words, I feel "Note:" 
ought to be treated as 'markup' and the text ought to be capitialisation 
correct within it.
