[docs] [issue11975] Fix referencing of built-in types (list, int, ...)

Jonas H. <jonas@lophus.org> added the comment: I'm not. My patch doesn't address the problem of unlinkable methods but wrong type declarations (read, wrong usage of ".. function::" directives) for builtins like int, float, bool, list etc. Because the directives change, the roles used to link to them (":func:`list`") have to be changed accordingly. That's what this patch does. I want to address `list` method documentation in the next step. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue11975> _______________________________________
