Without [ code ] tags:
ExampleSame text, with [ code ] tags:
<a href="http://example.com/">Examplea>
I haven't dug into the code yet to see why this is happening.
I think that the [ code ] tag should preserve the contents as-is, with only a couple of exceptions: 1) line-wrap to prevent excessively long lines, and 2) [ color ] tag interpretation to allow highlighting when posting code changes. Both of those exceptions seem to work ok.
