Numbered paragraph, unnumbered, numbered-- oops!

[Steve Gerber]

Entering a comment in WordPress, one of my users stumbled upon an 
interesting problem with PHP Markdown:

1. You write a numbered paragraph.

You write a second, unnumbered paragraph to elaborate.

1. You another numbered paragraph, and the numbering resets to 1, 
even if you number the paragraph 2.

I understand what's going on here, with PHP Markdown interpreting 
each of the two numbers as the beginning and end of an ordered list, 
but it's difficult to explain that to users.  Is there any way around 
this behavior?
