[Animated GIF] Bug

Steps:
1.
    var img = new Image;
    img.src = "http://33.media.tumblr.com/tumblr_m6t5rzAfVU1qc0s10o1_500.gif";
    img;
2. Click on the logged console message to select it
3. Press Command-C to copy it

Expected clipboard content: 
<img src="http://33.media.tumblr.com/tumblr_m6t5rzAfVU1qc0s10o1_500.gif">

Actual clipboard content:
<img src=​"http:​/​/​33.media.tumblr.com/​tumblr_m6t5rzAfVU1qc0s10o1_500.gif">​
 = $1

1. There are a few zero-width spaces (\u200B) in the copied message; they are marked as red dots if you paste this message to the console prompt (see the attached image).

2. " = $1" shouldn't be copied.

[Timothy Hatcher]

WebInspector._copy should already be doing this, I guess it isn't being called?

    // Remove word break characters from the selection before putting it on the pasteboard.
    var selectionString = selection.toString().removeWordBreakCharacters();
    event.clipboardData.setData("text/plain", selectionString);
    event.preventDefault();

No need for the () in the regex.

[Devin Rousso]

Should this also remove console information?  For example, entering

console.log("test");

If I copy the resulting line (which should just say "text") and paste it, I get

[Log] test

Should that [Log] be there?  I have also seen source location information at the end for functions.

[Timothy Hatcher]

[Log[ is added on purpose. The location is also added. I think it makes sense to strip out the = $n parts.

Wait, never mind. I think $n should stay. If you use $n in a future line (like $2.foo.bar), you want to be able to look back and see where it came from. So remote this stripping.

By the way, I added this so that, as seen in Nikita's example, the " = $1" doesn't wrap to the next line.

Oh, you were stripping before. Now you just strip linebreaks there. Nice!
