[Bug-wget] Wget bug - srcset

[Bence Bojti]

Dear Developers!

I have a problem with the Wget 1.18 (installed from standard repo of Debian
9).

I need wget to mirroring a website with --page-requisites.

Unfortunately on my website, which I want to mirror ( https://mno.hu ),
there are lot of <picture> tag with a few <source srcset="...">. This is
valid html5 code.

For example:

<picture>
    <source media="(min-width: 1238px)" srcset="/test/1.jpg">
    <source media="(min-width: 926px)" srcset="/test/2.jpg">
    <source media="(min-width: 614px)" srcset="/test/3.jpg">
    <img src="/test/4.jpeg" alt="Alt text">
</picture>

In this situation the wget doesn't download the images given in the srcset.
Just the img src.

On this page https://savannah.gnu.org/forum/forum.php?forum_id=8568 I can
read, that the version 1.18 can handle the srcset: "Parse <img srcset>
attributes on a recursive download. ".

But I dont know that this refers just to the srcset within the <img> tag,
and not the <source>, or this is a bug in this release. But all the same.
It would be great, if wget would follow the new html stanards, 'cause I
cannot use so now for my site. :(

Best regards!
