Parentheses now appear wherever they would in the Python code.  Also, multiple optional arguments are shown as [arg1 [, arg2]] since by Python rule you can omit only consecutive arguments from the right end.  (Having them individually bracketed makes it appear that they can be individually omitted.)

I have no opinion on whether this is desirable or not; I will go with
whatever others think.  Python is a read-only language for me.

On the pure Texinfo side, in addition to the typo spotted by Pedro, I
have the following comments:

> -@defun execute command [from_tty] [to_string]
> +@defun execute (command @r{[}, from_tty @r{[}, to_string@r{]}@r{]})

You can mark several `]' characters together, like this:

  @defun execute (command @r{[}, from_tty @r{[}, to_string@r{]]})

There are several of these in the patch.  What you did is not wrong,
though.

> -@defmethod Value string @r{[}encoding@r{]} @r{[}errors@r{]} @r{[}length@r{]}
> +@defmethod Value string (@r{[}encoding@r{[}, errors@r{[},
> +length@r{]}@r{]}@r{]})

You cannot break any of the @def* lines, they all must be a single
line, even if it is long (here and elsewhere).

Finally, please note that the way you put the parentheses (..) in the
@def* directives, they will be typeset in slant typeface (I think).
So please make a PDF or PS output and eyeball it to make sure you like
the result.  If you don't like it, you can use @r{(} and @r{)} like we
do with square brackets.

Thanks.
