✓ a = a + x ==> a+=x

should warn too;
JS is so sloppy that this could be an indication of a bug.
*******
x, x ==> x
x = foo, x ==> x
other similar cases?
*******
Try to concatenate all scripts somehow before starting minification;
the issue will be keeping track of the current source file for
generating source maps. perhaps store that in the AST? Have a single
AST_Toplevel for all files.
XXX? Not sure if this is worth the trouble.

discard spurious break statements

The following seems to compress suboptimally. Should probably run more
passes somewhere.
function setOpacity(el, o) {
if (o != null) {
if (o == "" && o != 0) {
is_ie
? el.style.filter = ""
: el.style.opacity = "";
} else {
is_ie
? el.style.filter = "alpha(opacity=" + Math.round(o * 100) + ")"
: el.style.opacity = o;
}
return o;
} else {
if (!is_ie)
return parseFloat(el.style.opacity);
else
if (/alpha\(opacity=([0-9.])+\)/.test(el.style.opacity))
return parseFloat(RegExp.$1);
}
