Avoid too long words in a post title, post content or comment but only if its not a url

Thank you Milo,

“word-break” alone wasn’t enough as it’s css3 only and not cross-browser.

But I found this:

.bloc_content{
    overflow:hidden; 
   -ms-word-break: break-all;
    word-break: break-all;
    word-break: break-word;
   -webkit-hyphens: auto;
   -moz-hyphens: auto;
    hyphens: auto;
}

It seems to to work in all cases I tested.
Hopefully it would be cross-browser enough to solve the problem.
Not sure if it would resist to old browsers though…
