  /**
   * Pop the RTFDTM's context mark. This discards any RTFs added after the last mark was set.
   *
   * <p>If there is no RTF DTM, there's nothing to pop so this becomes a no-op. If pushes were
   * issued before this was called, we count on the fact that popRewindMark is defined such that
   * overpopping just resets to empty.
   *
   * <p>Complicating factor: We need to handle the case of popping back to a previous RTF DTM, if
   * one of the weird produce-an-RTF-to-build-an-RTF cases arose. Basically: If pop says this DTM is
   * now empty, then return to the previous if one exists, in whatever state we left it in. UGLY,
   * but hopefully the situation which forces us to consider this will arise exceedingly rarely.
