annotate move-if-change @ 4717:fcc7e89d5e68

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Properly handle continuable divide-by-zero errors. Fix truncation of a zero-valued ratio. See xemacs-patches message <870180fe0910080956h5d674f03q185d11aa6fc57bd2@mail.gmail.com>.
