I doubt that this kind of line breaking style is actually proper rst.
If you mean wrapped lines, it is wrapped by email client (in sent messages it looks as a table). But really, this rst (original version from sent messages) doesn`t work (I actually test it) and don`t know why, but problem is probably related with linebreaks.
In last wersion of diff is pset changed from linestyle to format and using "wrapped" format is not possible.
