I'm wondering if this is a bug or if I'm missing something.
The selector $('span[class^="err"]') matches <span class="error"> but
*not* <span class="err-2">.
$('span[class^="err-"]') does *not* match <span class="err-or"> or
<span class="err-2">What's the deal with the hyphen? Is it a special character?
