Bug: Code block after list

[Lou Quillio]

Maybe this has been reported before, but I can't find it in the
archives.

A code block immediately following an ordered or unordered list
breaks both the list and the code block.  Badly.

Tab or spaces for the block don't matter, legal indentation variants
of the list don't matter.  Tried a bunch of casual workarounds,
extra newlines, etc., but no joy.  Needs explicit <pre><code> --
which also fixes the preceding list, however Markdown then wraps the
<pre> block in a paragraph.  PHP Markdown Extra does not.

Reproducible in current Markdown, PHP Markdown Extra, and Maruku.
