auto_link should not linkify URLs in the middle of a tag

Do not need

The last comment was about a href=" check, because it's in the middle of a tag either.

Just ran into this, upgrading an app from 2.2 to 2.3.

auto_link('') in 2.2: auto_link('') in 2.3: auto_link('http://google.com/image.jpg" />')

Let's try that again.

auto_link('<a href="http://google.com"><img src="http://google.com/image.jpg" /></a>')

in 2.2:

<a href="http://google.com"><img src="http://google.com/image.jpg" /></a>

in 2.3:

<a href="http://google.com"><img src="<a href="http://google.com/image.jpg">http://google.com/image.jpg</a>" /></a>

Good catch -- it definitely slipped my mind.

I would only change the check like this:

if left =~ /<[^>]+$/ && right =~ /^[^<]+>/

Now the right regexp reflects the left.
