That's not how it's implemented now. The code actually iterates through 
all the modules and dumps each one in turn.

       result.GetOutputStream().Printf("Dumping clang ast for %" PRIu64
                                       " modules.\n",
       for (size_t image_idx = 0; image_idx < num_modules; ++image_idx) {
         if (m_interpreter.WasInterrupted())
         Module *m = target->GetImages().GetModulePointerAtIndex(image_idx);
         SymbolFile *sf = m->GetSymbolVendor()->GetSymbolFile();

In fact, it looks like this command already supports specifying the 
exact module to dump (either by basename or full path).
