Some of wiki html validation errors come from redcloth3.

There is function blocks( text, deep_code = false ) in lib/redcloth.rb. (It parses wiki content into html blocks.)
Each paragraph is placed into <p></p> tag. (So we have <p>some_paragraph</p>.)

All is well unless the paragraph contains macros. (<p>some_text{{some_macros}}some_text</p>)
In some cases the content of the paragraph after execution of all macroses will be too long. (<p>some_text some_html(could be in more than one paragraph) some_text</p>)
Then the browser autocompletes the opening <p> tag. (Now we have <p></p>several_paragraphs</p>.)
The closing tag </p> leads to validation error.

I've tried to change the line

blk = "\t<p>#{ blk }</p>"

into

blk = "\t<div>#{ blk }</div>"

but the browser drawing of <div> tags content is different from <p> tags.

Then I've added class "paragraph_like":

blk = "\t<div class=\"paragraph_like\">#{ blk }</div>"

and added CSS in public/stylesheets/application.css

.wiki div.paragraph_like {margin: 12px 0px 12px 0px;}

And it looked almost like <p> tags.

Is such solution acceptable?
