Thanks for the references - I'm afraid it's not a question I've looked to much into, as my research is currently focusing on 1791-1792 and principally on the journal the "Révolutions de Paris." I've observed in the sources I've have been looking at that direct quotations are rare and long ones almost non-existent (when they come up they're usually a line or two long). So it doesn't surprise me that that would be the case more generally as well. Still, all the quotations I've found so far can be traced back to their original sources in roughly the same form. Which just makes Desmoulins' claim to simply be offering a translation of Tacitus all the more disingenuous...
