* Text: wrap lines where PowerPoint does - Without latinLnBrk (PowerPoint's default) a word doesn't break after '/' or '\': URLs and paths fill the line and break at its edge. - Korean wraps between words, not between syllables. - With hangingPunct, closing East Asian punctuation hangs past the end of the line instead of dragging the previous character down. ParaProps gains latin_line_break and hanging_punct, read and written as latinLnBrk and hangingPunct.
