annotate include/mb_backend.h @ 1401:2fc1f54a1a3b

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Mainly fix the clone_from_subtree to update the children of the parent node. We need to clearify all related codes in the future to make the logic more clear.
