Ok. But the reverse mapping will help with this, won't it? We'll look up the interesting commits and find their associated note objects directly. BTW, if you use "git-note -l <commit>" it'll go directly to <commit>'s subdir in refs/notes and never look at any other notes. Of course, this currently does not help the plumbing much, which uses for_each_note_ref() instead... ...Johan -- Johan Herland, <johan@xxxxxxxxxxx> www.herland.net - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
