Locale dependent formatting of lists.

The default locale for the functions in this module is determined by the
    following environment variables, in that order:

* ``LC_ALL``, and
     * ``LANG``

    """
    Format the items in `lst` as a list.

>>> format_list(['apples', 'oranges', 'pears'], locale='en')
    u'apples, oranges, and pears'
    >>> format_list(['apples', 'oranges', 'pears'], locale='zh')
    u'apples\u3001oranges\u548cpears'

    u'omena, peruna tai aplari'

These styles are defined, but not all are necessarily available in all locales.
    The following text is verbatim from the Unicode TR35-49 spec [1].

* standard:
      A typical 'and' list for arbitrary placeholders.
      eg. "January, February, and March"
    * standard-short:
      A short version of a 'and' list, suitable for use with short or abbreviated placeholder values.
      eg. "Jan., Feb., and Mar."
    * or:
      A typical 'or' list for arbitrary placeholders.
      eg. "January, February, or March"
    * or-short:
      A short version of an 'or' list.
      eg. "Jan., Feb., or Mar."
    * unit:
      A list suitable for wide units.
      eg. "3 feet, 7 inches"
    * unit-short:
      A list suitable for short units
      eg. "3 ft, 7 in"
    * unit-narrow:
      A list suitable for narrow units, where space on the screen is very limited.
      eg. "3′ 7″"
