Precedence of "locale-dictated format" not mentioned for `MONTH_DAY_FORMAT` and `YEAR_MONTH_FORMAT` settings

[James Beith]

When reading the documentation for ​SHORT_DATE_FORMAT, and other similar Globalization (i18n/l10n) settings, there is a mention about the use of USE_L10N.

Note that if USE_L10N is set to True, then the corresponding locale-dictated format has higher precedence and will be applied.

However when I was reading the ​MONTH_DAY_FORMAT and ​YEAR_MONTH_FORMAT settings there was no mention about USE_L10N.

I was left unsure as to whether the value of USE_L10N affected these two settings. It could be worth mentioning explicitly whether it does or not so the reader is clearly aware.

I've verified the current behavior by creating a simple AdminModel model.

class MyModelAdmin(ModelAdmin):
    list_display = ('name', 'pub_date')
    list_filter = ['pub_date']
    date_hierarchy = 'pub_date'
