Basically, when I use a code snippet like below, that I've likely pasted in from another document:

<pre><code>fn main() {    println!("Hello World"!);}</code></pre>

Line 1 (usinghljs.initLineNumbersOnLoad();) will always be blank, as it registers the line break after the<code> tag as a new line.

It's easy enough to fix, it's just a little annoying.

Describe the solution you'd like
Optionally remove the first line from the code block if it's empty.

Describe alternatives you've considered
Technically you can do this:

<pre><code>fn main() {    println!("Hello World"!);}</code></pre>

But it looks a little gross to me idk.

Not a high priority by any means, but I think it would feel nice :)
