In the Python API, Type.template_argument(n) returns either a gdb.Type
or a gdb.Value, depending on whether the n'th template argument is a C++
type or a C++ value.

Also add a note that Type.template_argument(n) throws an exception if n
is out of range (as opposed to, say, returning None).

There's one piece of the documentation I still don't understand:

> If block is given, then name is looked up in that scope. Otherwise, it
> is searched for globally.

What is 'name', exactly, and why are we looking it up?  I'd be happy to
fix this up if we could clarify this, but otherwise this patch stands on
its own.

2014-06-18  Justin Lebar <jlebar@google.com>

	* python.texi (Types In Python): Type.template_argument(n) returns a
	gdb.Value or a gdb.Type and throws an exception if n is out of
	range.

Ping on this patch?  (Would it be appropriate to find the last person
to touch this documentation and cc him/her, or do something else like
that?)

Regards,

No, Eli is the person to review this patch, not the last person to
touch it. Maybe he is away at the moment.

I'm not away, I just remembered that I already reviewed this patch and
responded with the review on the same day.

It looks now that my response didn't make it to the list for some
reason, because I see it in my FCC archive, but not in the list
archives.

So here's my response as I wrote it back then:

  @var{n}

  Otherwise, the patch is OK Texinfo-wise; I don't know enough about
  these issues to tell whether the content is correct, nor can I answer
  your question.

  Thanks.

Indeed, and although there may have been a problem with the list, I
got your response and sent a fixed patch.  But maybe I misunderstood
your response?

I thought this indicated I should wait for someone else to chime in?
Or were you saying this was OK to submit with this change?

Sorry, I'm obviously new here.  :)

You understood correctly.  Since you are correcting existing
documentation, I think it would be good if someone who knows that
stuff looked at the corrections from the contents point of view and
approved them.

Thanks.

Content-wise, the patch is ok with me.

Can we finally submit this patch, or is there something else I need to do here?
