Problem in loading QM translations with LANGUAGE="" envar

[Safa Alfulaij]

More investigation shows that it does not work with other locales than the
default one (the one that is used in case you don't pass a country code,
which, in case of Arabic, is ar_EG).

[safa at archlinux]$ LANG=ar_BH.utf8
> [safa at archlinux]$ python testQtLocale.py
> b'\xd9\xa2\xd9\xa0 B'
> [safa at archlinux]$ LANG=ar_EG.utf8
> [safa at archlinux]$ python testQtLocale.py
> b'\xd9\xa2\xd9\xa0 \xd8\xa8\xd8\xa7\xd9\x8a\xd8\xaa'
> [safa at archlinux]$ LANG=ar_SA.utf8
> [safa at archlinux]$ python testQtLocale.py
> b'\xd9\xa2\xd9\xa0 B'
> [safa at archlinux]$ LANG=ar_TN.utf8
> [safa at archlinux]$ python testQtLocale.py
> b'20 B'


Notice the translated version of "B" in ar_EG. The locale is set correctly
as we can see ar_TN uses the correct English/Arabic (not Hindi) numbering
system.
So it seems that the files are registered for that ar_EG locale only, which
is causing the trouble.

Note: Qt prioritizes LANGUAGE which has no country code, and that was the
problem. I'll be sending a small patch to use LANG if the first choice in
LANGUAGE is the same as LANG's main language.
