Bug#411082: locale preseeding doesn't work for country

[Robert Millan <rmh@aybabtu.com>]

Package: localechooser
Severity: normal

There seems to be currently no way to preseed country.  When preseeding
it via "locale", it'll fallback to whatever is the default country for
this language.

E.g. locale=en_AU results in en_US being used, etc.

Relevant portion of the log:

Feb 15 21:11:09 localechooser: info: Locale has been preseeded to en_AU
Feb 15 21:11:10 localechooser: info: Set languagechooser/language-name = 'English'
Feb 15 21:11:10 localechooser: info: Set countrychooser/shortlist-en = 'AU'
Feb 15 21:11:10 localechooser: info: Set debian-installer/locale = 'en_AU'
[ ". languagemap" starts ]
Feb 15 21:11:10 localechooser: info: LANGNAME=English
Feb 15 21:11:10 localechooser: info: line=English;0;en;US;en_US.UTF-8;;kbd=lat0-sun16(utf8)
[ ". languagemap" ends]
Feb 15 21:11:10 localechooser: info: Set debian-installer/language = 'en'
Feb 15 21:11:10 localechooser: info: Set debian-installer/locale = 'en_US.UTF-8'
Feb 15 21:11:10 localechooser: info: Set debian-installer/fallbacklocale = 'en_US.UTF-8'
Feb 15 21:11:10 localechooser: info: Set debian-installer/country = 'US'
Feb 15 21:11:10 localechooser: info: Set debian-installer/consoledisplay = 'kbd=lat0-sun16(utf8)'
Feb 15 21:11:10 debconf: Setting debconf/language to en
Feb 15 21:11:10 localechooser: info: Set debconf/language = 'en'
Feb 15 21:11:10 localechooser: info: Set countrychooser/country-name = 'United States'
Feb 15 21:11:11 localechooser: info: Set debian-installer/country = 'US'
Feb 15 21:11:11 localechooser: info: Set debian-installer/locale = 'en_US.UTF-8'

It seems that languagemap is screwing things up.  It sets the $LOCALE
variable to its fallback value from $line without taking into account
that $LOCALE might have been set earlier in do_preseed.
