Markdown newline rendering broken
As per the specs Markdown should not insert <br /> for single line breaks. <br /> should only occur for:
- A line ending with 2 or more spaces, then a line break.
- One or more blank lines between paragraphs lines. In other words, 2 or more line breaks.
GitHub is consistent with this in wiki formatting. In GitHub issues a single line break also triggers a rendered line break, the reason for this is beyond me but that's also against the specs.
Please fix this. This actually breaks Pandoc conversion from Textile pages because Pandoc occasionally inserts line breaks even within paragraphs and this causes line breaks in the rendered text as well thus breaking the format.
