/**
* 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.
