Don't echo hreflang if returned value is empty

[reekrd]

Hi,

our site is translated into two languages and a subpart of it is translated into five languages.

We want to avoid having <link hreflang=...> to all languages on pages where content is only translated in english and dutch.

I have not installed the latest release so have not tried the new filter. But looking at qtranxf_wp_head if the returned value from the filter qtranslate_hreflang returns empty then don't echo <link hreflang=...>

Cheers and thank you for the excellent work

I was looking at code here: https://github.com/qtranslate/qtranslate-xt/blob/6837ebb4733a030fb0ef64f75ba0be59a747b9eb/qtranslate_frontend.php

I know I see that is not part of a release

It was a temporary attempt but I removed it as I wasn't so happy with it for the handling of the locales, in relation to #668 and #1030.

Your need is different as I can see in #1039 but I have to rethink this better to come up with a filter better suited for all cases.

Closed by #1039 (still to be done).
