   /* This is a hack for the gas/all/redef2.s test.  This test causes symbols
      to be cloned, and without this test relocs would still be generated
-     against the original pre-cloned symbol.  Such symbols would not appear
+     against the original, pre-cloned symbol.  Such symbols would not appear
      in the symbol table however, and so a valid reloc could not be
      generated.  So check to see if the fixup is against a symbol which has
      been removed from the symbol chain, and if it is, then allow it to be
      adjusted into a reloc against a section symbol. */
