Bash does most of the locale-setting itself for two reasons.
1. setlocale() calls getenv() to obtain the values for the variables it's
interested in. Not all systems allow getenv() to be replaced or
interposed, so setlocale() would see stale data.
2. Users expect shell variables to affect the locale for the shell. Since
setlocale() looks in the environment, these changes would not be
applied.
In any event, calling setlocale(LC_ALL, default_locale) is rarely the right
thing to do, since it doesn't allow users to mix locales between categories
(e.g., LC_COLLATE=C; LC_CTYPE=C; LC_MESSAGES=de_DE.UTF-8).
