Multiline list items

[sheep]

Would be nice to have:

* First item
* Second item is long, so I'm
continuating it on the second line
* Third item

renders:

• First item
• Second item is long, so I'm continuating it on the second line
• Third item

instead of

• First item
• Second item is long, so I'm

continuating it on the second line

• Third item

I won't put this in Hatta's default markup, because you are supposed to predict how each line will look without looking at other lines (except for preformatted blocks).

It can be implemented in an extension though, if there is any taker.
