Markdown Discuss - Feb 2008 - Entity conversion glitch?

Hello,

Given the following text:

under a license from AT&T; however, others were based on BSD instead.

Daring Fireball's Markdown Dingus produces:

<p>under a license from AT&T; however, others were based on BSD  
instead.</p>

Note how the '&' is not escaped to '&amp;'.

Bug? Feature?

Thanks in advance.

Kind regards,

PA.

   I'd guess "design" -- &T; isn't a very good html
entity, but
   it matches &[a-zA-Z0-9]+;

I would say this is a minor bug, and an interesting edge case as well.
The cause is the semi-colon following the `T`. `&T;` looks like an
html entity. If you remove the semicolon, the `&` is properly
converted to `&`.

In python-markdown, you can escape the `&` and you will get the expected
output:

    under a license from AT\&T; however, others were based on BSD instead.

becomes:

    <p>under a license from AT&amp;T; however, others were based on
BSD instead.
    </p>

Unfortunately, this does not seem to work in the other implementations.
