External templates break syntax highlighting

[ThomasKientz]

Info

• Platform: macOS
• Vetur version: 0.12.3
• VS Code version: 1.23.1

Problem

<template 
  src="./mission.html" 
  lang="html"/>

<script>
//code not being highlight
<script>

Breaks syntax highlighting (and maybe formating too)

But this is using recommended vue's es-linting rules.

2 things is causing the break :

• / inside src attribute.
• multi lines

<template src="./mission.html"></template>

<script>
</script>

@octref This works but doesn't respect enforce self-closing style (vue/html-self-closing) from vue recommended style.

That does not concern the enclosing region divider. However the syntax highlight does have some problem now...

I'll just make sure this works:

<template src="./mission.html" />

I will never support multiline.

[octref]

This is now supported:

Multi line is not possible without a lot of hacks, so I'll pass on that.

Just to link to microsoft/vscode-textmate#32 on why mutiline is almost impossible.
