If I understand you correctly, and I'm far from sure that I do, I think you are suggesting that you could send a shorter reference to a location that then would either forward the request to the longer url, or simply display it for the user to click upon.

If this is the gist of your suggestion, frankly, it sounds like quite a lot of extra complexity for such a small problem.

Perhaps you should ask your users how they would like to deal with this problem, since chances are reasonable that they have encountered it before, as most web users - especially users of web based email - have encountered text-wrapped urls at some time or another.

If someone asked me whether I would prefer to manually fix these text-wrapped urls or deal with an intermediate reference, like the one you seem to be suggesting, I would choose the former.
