Repository: sveltejs/prettier-plugin-svelte (ts)

Issue:
Empty style and script tags are expanded into three lines
I'm using Svelte with svelte-preprocessor. The following lines:

```html
<script src="./index.ts"></script>

<style src="./index.css"></style>
```

is formatted as:

```html
<script src="./index.ts">

</script>

<style src="./index.css">

</style>
```

My expected output should be the same as first one. Is this some kind of bug?

Thanks!

Pull request:
Make it possible to have script/style without newline
If the content of a script/style tag is completely empty (no whitespace), don't add a hardline anymore.
Fixes #87
