Emmet completions

[etune]

I use Vue Single File components that have a stylus section...

<style lang="stylus">
  .foobar
    // m0 -> tab -> doesn't work
</style>

The syntax highlighting works, but emmet completions do not. Tab completions work in regular stylus files.

If you think this needs to posted here, please let me know. https://github.com/vuejs/vue-syntax-highlight

Thanks!
