Does the `pymoptions=""` attribute actually support backslashes?

[benlk]

We have this example in readme.txt:

[pym src="child.html" pymoptions=" xdomain: '\\*\.npr\.org' "]

Which is supposed to output: (with supporting code)

pym.Parent('pym_0', 'child.html', { xdomain: '*\.npr\.org' });

But what it actually puts on the page is this:

pym.Parent('pym_0', 'child.html', { xdomain: '\*.npr.org' })

Inside, the $pymoptions variable is this:

error_log( var_export( $pymoptions, true ) );
' xdomain: \'\\*.npr.org\' '

If we esc_js() that, it's this, still not what we're looking for:

' xdomain: \\\'*.npr.org\\\' '

In conclusion: slashes aren't being output correctly.
