Github Flavored Markdown

Works in conjunction with the Markdown module to provide additional functionality to the Markdown syntax as per http://github.github.com/github-flavored-markdown/

Features

Hard Wrap Single Newlines
Treat single newlines in paragraph-like content as line breaks. This is more intuitive for most users than the way in which Markdown normally handles single newlines.

Escape Underscores in Words
It is not reasonable to italicize just part of a word, therefore words containing multiple underscores have their inner underscores escaped. This foo_bar_baz does not turn into foobarbaz.

Fenced Code Blocks
Markdown supports delineating code blocks by beginning each line with four spaces or a tab character. This can be cumbersome when entering longer snippets, so GFM implements fenced code blocks -- text encapsulated by '```' (three backticks) are treated as if each line began with four spaces or a tab character.

Auto Linking of Raw URLs
Github Flavored Markdown attempts to find raw URLs within the text and format them as Markdown style links so they are later transformed into HTML anchor tags -- clickable links -- by the Markdown processor.
