character sequence. (Only used in _v2 or later.)
p[i] = UC_BREAK_POSSIBLE means that a line break may be inserted between
s[i-1] and s[i].
p[i] = UC_BREAK_HYPHENATION means that a hyphen and a line break may be
inserted between s[i-1] and s[i]. But beware of language dependent
hyphenation rules.
p[i] = UC_BREAK_PROHIBITED means that s[i-1] and s[i] must not be separated.

/* Choose the best line breaks, assuming the uc_width function.
The string is s[0..n-1]. The maximum number of columns per line is given
as WIDTH. The starting column of the string is given as START_COLUMN.
If the algorithm shall keep room after the last piece, they can be given
as AT_END_COLUMNS.
o is an optional override; if o[i] != UC_BREAK_UNDEFINED, o[i] takes
precedence over p[i] as returned by the *_possible_linebreaks function.
The given ENCODING is used for disambiguating widths in uc_width.
Return the column after the end of the string, and store the result at
p[0..n-1].
