Offer i18n for internal templates

[giggio]

Some internal templates are in English only. It would be important that they offer an option to use i18n, or fallback to a default value in English.

Examples: The pagination template has several terms in English. This one is even more important, as it is an aria- element:

https://github.com/gohugoio/hugo/blob/52561d561a591a6fb757b6d417138e0a79bce790/tpl/tplimpl/embedded/templates/pagination.html#L79

The disqus template "powered by" message is not i18n: https://github.com/gohugoio/hugo/blob/52561d561a591a6fb757b6d417138e0a79bce790/tpl/tplimpl/embedded/templates/disqus.html#L22

The rss template also has some sections only in English: https://github.com/gohugoio/hugo/blob/52561d561a591a6fb757b6d417138e0a79bce790/tpl/tplimpl/embedded/templates/_default/rss.xml#L38

These are only some examples, there are others. There is need to find them, make a more complete list, then solve each of them. I believe this issue could be used to discuss how this will be approached.

I've used this construct before:

{{ or (T "key") "default" }}

But keep in mind that neither the --printI18nWarnings flag nor the enableMissingTranslationPlaceholders configuration setting care if you have a fallback value. If you don't have an entry in the translation table, the first will throw a warning and the second will replace the rendered fallback value with [i18n] key.

Arguably that's the correct behavior, but as soon as we change the embedded templates, those who use the --printI18nWarnings are going to see warnings they've never seen before.

I was thinking about something like that, yes.

If the user is asking for i18n warnings they'd want to have that information. Users who are only building in a single language wouldn't be bothered, as I imagine they wouldn't be using that flag.

I copied the pagination template and added the keys myself. Maybe you should try that approach.

@tycobrah I am not thinking of only myself, but as a benefit for the whole community. But if you've already done it, you could send a PR.

I translated to my own secondary language. Joe's approach seems better coz I only copied the terse section and extensively modified it.
