Exclude sensitive tags from typographic enhancement.
Exclude sensitive tags from typographic enhancement.

In addition to `script` tags, `pre`, `code`, `kbd` and `math` should be excluded from typographic enhancement. These tags are typically used to present whitespace sensitive text, or other text where typographic enhancement is not appropriate. This list is consistent with the tags excluded from SmartyPants/RubyPants.

`ignore_scripts` and `@ignore_scripts` should probably be renamed to something more descriptive.
