vB will take a long link and shorten the *text* that is shown, but not the url link part. Like for this post:

It shows as shortened, but hover over it and it is complete. Now, if somebody just copies the text and pastes it in a non WYSIWYG editor, it will be wrong. But, it should be fine copied into a WYSIWYG editor or if they do a Copy Link instead of just a regular copy text on it.
