Function format_note

notes.c:1280–1340

* Fill the given strbuf with the notes associated with the given object. * * If the given notes_tree structure is not initialized, it will be auto- * initialized to the default value (see documentation for init_notes() above). * If the given notes_tree is NULL, the internal/default notes_tree will be * used instead. * * (raw != 0) gives the %N userformat; otherwise, the note message is give

 * for human consumption.
