revlog: in addgroup, reject ill-formed deltas based on censored nodes To ensure interoperability when clones disagree about which file nodes are censored, a restriction is made on deltas based on censored nodes. Any such delta must replace the full text of the base in a single patch. If the recipient of a delta considers the base to be censored and the delta is not in the expected form, the recipient must reject it, as it can't know if the source has also censored the base. For background and broader design of the censorship feature, see: http://mercurial.selenic.com/wiki/CensorPlan
