def fill_breakable(sep=' ', width=sep.length)
group { breakable sep, width }
end
This is similar to breakable except the decision to break or not is determined individually.
Two fill_breakable under a group may cause 4 results: (break,break), (break,non-break), (non-break,break), (non-break,non-break). This is different to breakable because two breakable under a group may cause 2 results: (break,break), (non-break,non-break).
The text sep is inserted if a line is not broken at this point.
If sep is not specified, “ ” is used.
If width is not specified, sep.length is used. You will have to specify this when sep is a multibyte character, for example.
