Extend TextWrapper for Unicode.
This textwrapper handles east asian double width and split word
even if !break_long_words when word contains double width
characters.
:param ambiguous_width: (keyword argument) width for character when
unicodedata.east_asian_width(c) == 'A'
(default: 1)
Limitations:
* expand_tabs doesn't fixed. It uses len() for calculating width
of string on left of TAB.
* Handles one codeunit as a single character having 1 or 2 width.
This is not correct when there are surrogate pairs, combined
characters or zero-width characters.
* Treats all asian character are line breakable. But it is not
true because line breaking is prohibited around some characters.
(For example, breaking before punctation mark is prohibited.)
See UAX # 14 "UNICODE LINE BREAKING ALGORITHM"

Correct for sentence endings buried in 'chunks'. Eg. when the
original text contains "... foo.
Bar ...", munge_whitespace()
and split() will convert that to [..., "foo.", " ", "Bar", ...]
which has one too few spaces; this method simply changes the one
space to two.
Note: This function is copied from textwrap.TextWrap and modified
to use unicode always.

Reformat the single paragraph in 'text' so it fits in lines of no
more than 'width' columns, and return a list of wrapped lines. By
default, tabs in 'text' are expanded with string.expandtabs(), and
all other whitespace characters (including newline) are converted to
space. See TextWrapper class for available keyword args to customize
wrapping behaviour.
