New submission from Eli Bendersky <eliben at gmail.com>:

The following minor issues may affect the readability of the code implementing symbol tables in Include/symtable.h and Python/symtable.c

    * The comment for st_global in symtable.h says: "borrowed ref to st_top->st_symbols. typo? (st_top->ste_symbols)
    * ste_varnames: the name and the comment after it are misleading, since it actually collects only the function's parameters and not all variables.
    * the st_nblocks and st_future fields of symtable aren't used anywhere - py3k compiles fine when they're removed.
    * in analyze_block a comment says "Recursively call analyze_block()" - untrue, probably meant analyze_child_block. While technically analyze_child_block calls analyze_block, the comment as-is appears misleading.
    * symtable_add_def is also called with the USE flag, not only definitions, hence its name doesn't reflect its purpose accurately
    * There are some indentation artifacts that obscure readability. For example the case Raise_kind of symtable_visit_stmt, where two nested blocks start and end in the same column obscuring the fact they're nested. This could be a result of an automatic tab to space conversion in the past.
