[dokuwiki] Result of running http://www.jslint.com/ on the 'captcha' plugin's file named 'script.js'

Here's the result of an on-line tool that checks
javascript, when asked to check the "captcha"
plugin's file named "script.js".

I first pointed my web browser at 

    http://www.jslint.com/

Then I copied and pasted the contents of
"scritp.js" into the web site's form.

Then I checked the "assume a browser" box.

I finally clicked on the button to run the on-line
tool.

The output follows below....

Thanks,
Kingsley
