Spurious warning for catch block parameter

[natevw]

If I run uglify using --lint on code like this:

try {
    throw up;
} catch (e) {}

It complains WARN: Symbol e is declared but not referenced. But the catch statement must have a parameter — if I could leave it out, I would but that would result in a syntax error (e.g. your parser gives ERROR: Name expected).

In my case with jQuery: $("a").each(function(idx, elem) { ... });, I only need the second argument, however. It complains WARN: Symbol idx is declared but not referenced.

Hmm... can't reproduce on current master (b5a7197)
