Issue #8 of WP Colored Coding describes a interoperability problem with another plugin which parses the_content
and didn't expect the occurrence of source code in the text.
This can be fixed by handling the WP-CC Shortcode after the_content
which is the normal way.
But this drops the support for in-text codes using the enclosing shortcode:
[cc lang="html"]
<strong>This will not longer be possible</strong>
