This issue was referenced by archive/flamenco-manager@a6e5900f0982217a7767b1ef1b42e49a4c29db01 at some point

Produces this output:

<p>This issue was referenced by<a href="/archive/flamenco-manager/commit/a6e5900f0982217a7767b1ef1b42e49a4c29db01" rel="nofollow">archive/flamenco-manager@a6e5900f09</a>at some point</p>

As you can see, there should be a space between by<a and also between </a>at.
