@HarHarLinks Could you please add some spaces and a slash for improved formatting?

This is how it looks.

This is how an alarm looks with spaces and a slash added.

@erebion thanks for the screenshots. I agree with your sentiment. However I'm not actively using this (just copy-pasted from the hookshot channel), I'm not even running Alertmanager, yet... I think it'd be best if you could suggest changes via code review?

@HarHarLinks Sure, I modified this slightly to look better so I can tell you what I did.

This is how it looks like with the changes, had to purposefully crash Grafana, lol

I'm happy, will give @erebion a bit of time to respond.

Looks okay, though I'd be a bit happier with an additional line break after [WARNING - FIRING] and before the source and silence link for improved readability and accessibilty.

Many people struggle to read such messages if they are a wall of text and have a much easier time if there's a line break.

Also, I think it looks a bit better.
