Large space between words when using links

[titanic]

Hello.
I have a problem, when I use full alignment, that looks like the second example in this attachment.
How do I solve this? It happens regularly.
Now, I don't want to add a space or a dash that will break the URL, because the url won't be the same that way. So, is there a solution to this?

By the way, I can't understand why in the first example the url was broken in between letters.
