JSMin, not being a real parser, has a tough time distinguishing between 
division and the beginning of a regexp literal, and after a line break the 
original algorithm has always assumed that "/" would start a regexp. Maybe this 
assumption needs some testing?

Open 
http://code.google.com/p/minify/source/browse/branches/2.1.4/min/lib/JSMin.php 
and try changing this:

        if (false !== strpos("\n{;(,=:[!&|?", $this->a)) { // we aren't dividing
            return true;
        }

to:

        if ($this->a === "\n") {
            return false; /* assume division */
        }
        if (false !== strpos("{;(,=:[!&|?", $this->a)) { // we aren't dividing
            return true;
        }

I'd need to see a lot of testing before I'd release such a change though.
