Recognition of URLs is unreliable

[mcepl]

I have this situation:

Talking about the left window (with #python:opensuse.org) and the bugzilla links are broken into so many lines, that my terminal doesn’t know what to do with them, and they don’t have any numbers attached to them either. The link in the other window (to https://ffmpeg-api.com/learn/ffmpeg/recipe/picture-in-picture seems) to be recognized just fine.
