[issue5815] locale.getdefaultlocale() missing corner case

[Mike FABIAN]

Mike FABIAN added the comment:

Serhiy, in your patch you seem to have special treatment for
the devanagari modifier:

+                # Devanagari modifier placed before encoding.
+                return code, modifier.split('.')[1]

Probably because of 

       'ks_in at devanagari':                     'ks_IN at devanagari.UTF-8',
       'sd':                                   'sd_IN at devanagari.UTF-8',

in the locale_alias dictionary.

But I think these two lines are just wrong, this mistake
is inherited from the locale.alias from X.org where the
python locale_alias comes from.

glibc:

mfabian at ari:~
$ locale -a | grep ^sd
sd_IN
sd_IN.utf8
sd_IN.utf8 at devanagari
sd_IN at devanagari
mfabian at ari:~
$ locale -a | grep ^ks
ks_IN
ks_IN.utf8
ks_IN.utf8 at devanagari
ks_IN at devanagari
mfabian at ari:~
$ 

The encoding should always be *before* the modifier.
