+Load two sheets, first with grp_refs to loclib; use the buffer to copy these
+grp_refs to the second sheet:
+  -> broken ref on the target buffer; three possible solutions:
+
+Possible solutions:
+
+1. on copy: convert group ref to group on copy and mark loclib-enable
+   -> BAD: this will break for non-loclib grp_refs
+
+2. on paste: remember group ref sheet on copy and if on paste there's a
+   mismatch, do a full copy
+   -> BAD: this will break if the source sheet is closed while grp_refs
+      are in buffer already!
+
+3. buffer could have an indirect subtree too, copy would fill it in
+   - on copy create indirect symlib in buffer and copy the loclib entry
+   - on paste compare indirects to the sheet's indirect hash, insert if needed
+   - all this done by loclib code; non-loclib grp_refs should be refused
