Function application in parentheses breaks syntax highlighting

[nathancarter]

Description

In literate mode, if a function application is inside a parentheses, then syntax highlighting becomes broken as shown below.

Steps to Reproduce

1. Create a new file.
2. Save it with the .litcoffee extension.
3. Enter the code below.

Example comments correctly highlighted

    ( foo bar ).baz()

Example comments incorrectly highlighted.

Expected behavior: Text without indentation should always be treated and highlighted as Markdown, never mistaken for Coffeescript code. GitHub highlights it correctly in the code shown above.

Actual behavior: The following screenshot shows that the syntax highlighter has begun to treat unindented code as if it were Coffeescript code.

Reproduces how often: 100%

Not sure if the root cause here is like that of #153 and #154 but they have the same result, so I'm linking them.
