Add option to hide en_US in wp_dropdown_languages()

[swissspidy]

While working on the ​Preferred Languages project I noticed that it's not possible to hide the English (United States) option in wp_dropdown_languages().

In my case, I do not need the en_US because of the way the UI works: When I do not pick a language from the dropdown, en_US will be the default. Screenshot: ​https://cloudup.com/cXhxw4KPqFc

While I added a workaround using JavaScript, I think there should be a) a show_option_en_US parameter or b) a filter (e.g. $output = apply_filters( 'wp_dropdown_languages', $output, $languages, $parsed_args )) at the end of the function. Or perhaps even both.

wp_dropdown_languages() already supports $args so I'm in favour of supporting another argument in that array to exclude certain locales by slug or something.

languages is also already supported though; I suppose you could reverse engineer it so you get the full list list of locales, then remove en_US and then use the updated list (minus en_US) to request as those specific locales. Not ideal, but serves as a better work around than JavaScript perhaps.

I've changed the ticket type to feature as it's not really a bug as nothing is broken here.

I've added a patch which adds an extra argument for en_US. Simple, but does the job.

Great, I agree this!

Needs updated docs and probably an other name (I'd really use show_option_... for consistency), otherwise 👍

@swissspidy: Do you still need this?

[swissspidy]

@pento Yep. Happy to land it for 5.1.
