Bug #6750

Comment above rb_iseq_struct.local_size gives out of date description

Description

The description of rb_iseq_struct.local_size says that it is sizeof(local vars) + 1 for class and method frames, but just sizeof(local vars) for block frames. I think this is no longer the case. local_size is always sizeof(local vars) + 1.

Here's the relevant code from when the comment was written (2007): https://github.com/ruby/ruby/blob/71986ef6bc232455deca67017873fff0c3cbd860/compile.c#L5004-5010
And here's the code today: https://github.com/ruby/ruby/blob/trunk/compile.c#L5571

I've attached a patch that fixes the comment.
