Description

The syntax highlighter gets confused and highlights source code content incorrectly.

Steps to Reproduce

Write a Rakefile like this:

VERSION = '0.0.1'
PROVIDER = 'virtualbox'
BOX_NAMESPACE = 'mcandre'

BOX_BASENAME = 'mucus'
BOX_BASENAME_MIPS64EL = "#{BOX_BASENAME}-mips64el"
BOX_BASENAME_MIPSEL = "#{BOX_BASENAME}-mipsel"
BOX_BASENAME_S390X = "#{BOX_BASENAME}-s390x"

BOX_MIPS64EL = "#{BOX_BASENAME_MIPS64EL}.box"
BOX_MIPSEL = "#{BOX_BASENAME_MIPSEL}.box"
BOX_S390X = "#{BOX_BASENAME_S390X}.box"

Expected behavior:

language-ruby highlights all bindings with one color, all raw string content with another color.

Actual behavior:

language-ruby highlights bindings inconsistently, and also highlights raw string content inconsistently.
