Correct spelling of Argentinian Spanish in global_settings.py

[aduston]

Argentinian Spanish is misspelled as "Argentinean Spanish" in django.conf.global_settings.LANGUAGES.

[Alex Gaynor]

Wikipedia lists "Argentinean" as a valid spelling, for what it's worth.

Yes, at the time I created the es_AR locale I had read some online English reference material and knew both were correct. I used to use 'Argentinean' then and later slowly changed to use 'Argentinian'.

You know, I filed this because of a bug report on my own project ( ​http://bugzilla.pculture.org/show_bug.cgi?id=13669 ) but since then I've done some research. It appears that Argentinian is the more common spelling, but it seems that Argentinean is not incorrect. I am wondering if I should withdraw the bug report here and mark the bug in our own tracker as invalid.

This is a bit of a bikeshed; I can find references supporting both.

Whenever I find a reference that lists E, it also lists I, but the opposite isn't always true. I've seen some reports that this is a US vs UK spelling issue, but I can't find any good confirmation of this.

The Shorter Oxford and the New American Oxford both list "i" exclusively, so I'll accept the ticket on that basis.

Of course, this completely sidesteps whether the correct grammar is "Argentine Spanish"... :-)

(In [13492]) Fixed #14064 -- Corrected spelling of Argentinian. There are arguments that it can be spelled both ways (and arguments that the right phrase is Argentine), but we're going with the OED on this one.
