Remove obsolete overflow check

...which had originally been added with 766d2b65
"INTEGRATION: CWS geordi2q10: #111934#: join CWS os21" as

-    rInf.Left( KSHORT(Left()) );
-    rInf.Right( KSHORT(Right()) );
-    rInf.First( short(FirstLeft()) );
+
+    // Handle overflows:
+    SwTwips nTmpLeft = Left();
+    SwTwips nTmpRight = Right();
+    SwTwips nTmpFirst = FirstLeft();
+
+    if ( nTmpLeft > USHRT_MAX ||
+         nTmpRight > USHRT_MAX ||
+         nTmpFirst > USHRT_MAX )
+    {
+        SWRECTFN( rInf.GetTxtFrm() )
+        nTmpLeft = (rInf.GetTxtFrm()->Frm().*fnRect->fnGetLeft)();
+        nTmpRight = (rInf.GetTxtFrm()->Frm().*fnRect->fnGetRight)();
+        nTmpFirst = nTmpLeft;
+    }
+
+    rInf.Left(  KSHORT( nTmpLeft  ) );
+    rInf.Right( KSHORT( nTmpRight ) );
+    rInf.First( KSHORT( nTmpFirst ) );

But later 2a2f9a30 "INTEGRATION: CWS
swqbugfixes10: #i34348# Underflow with negative numbering indent values" had
changed the SwTxtFormatInfo members from KSHORT to SwTwips, presumably obviating
the need for such an overflow check.
