grub-mkconfig locale vs. boot-time grub locale

Currently grub-mkconfig is using current (at the time of invocation)
locale to

1. output status messages during invocation
2. put translated messages (verbatim) into generated grub.cfg
3. set language in grub.cfg (set lang)

The problem is, user locale at the time of invocation does not
necessarily correspond to default system locale. This becomes even more
extreme as SSH and su/sudo often pass through locale environment
variables by default; so user locale may be inherited from unpredictable
value set on remote system.

Now imagine Chinese customer support employee remotely invoking
grub-mkconfig for European customer ...

It seems that case 1 and 2/3 should be treated differently. Suggestion
is

- export GRUB_LANG in grub-mkconfig for use in /etc/grub.d scripts.
GRUB_LANG is supposed to be set to system wide default. This may be set
by distributions in /etc/default/grub when system locale is changed or
determined dynamically from existing configuration.

- provide convenience wrapper for scripts in /etc/grub.d which basically
does LC_MESSAGES=$GRUB_LANG gettext ...

Does it sound sensible?
