Add invalid semicolon on multi-line for statements

[TiMESPLiNTER]

I tried to use the jsqueeze lib to compress my javascript in a Symfony framework application.

The library did something strange with this:

if ( !found ) {
    for ( found = [], elems = context.childNodes || context;
        ( elem = elems[ i ] ) != null;
        i++
    ) {
        // ...
    }
}

got squeezed into this:

if(!i){for(i=[],a=t.childNodes||t;(r=a[s])!=null;s++;){/*...*/}}

Firefox (v47.0) told me then: SyntaxError: missing ) after for-loop control
Chrome (v51.0.x) told me then: Uncaught SyntaxError: Unexpected token ;

In fact the the last semicolon is too much. When I change the compressed line to:

if(!i){for(i=[],a=t.childNodes||t;(r=a[s])!=null;s++){/*...*/}}

The squeezed javascript runs fine in both browsers.

(The line is from jQuery v1.12.4 (uncompressed, line 4557)
