The original code introduced with 1d10fb11 "New:
Text adjustment in multiportions" read

+            if( nMultiSpace < KSHRT_MAX )
+            {
+                pCurr->GetpSpaceAdd()->Insert(KSHORT(nMultiSpace),0);
+                bRet = sal_True;
+            }

so needed nMulitSpace to fit into KSHORT (an alias for USHORT back then),
whereas today nMultiSpace is inserted into a std::vector<long>.
