Strange behavior of newlines

>>> import mistune
>>> markdown = mistune.create_markdown()
>>> markdown('foo\n  bar')
'<p>foo\n  bar</p>\n'
>>> markdown('foo \n  bar')
'<p>foo \n  bar</p>\n'
>>> markdown('foo  \n  bar')
'<p>foo<br />\n  bar</p>\n'

I believe this is incorrect. The output should have a
between those two lines always, it shouldn’t depend on two spaces before newline.

I’ve added hard_wrap back into the master code.

This can be done with a custom InlineParser right now. But I think it would be good to make an option for it.
