I'm happy to take feedback and suggestions for improving the code,

Any word on performance differences from Michel's implementation?
No hard numbers yet; my intuition is that the Solar implementation
will be slower, due to the much larger number of files and separate
classes. The tradeoff is flexibility. I'll set up some benchmarks
and report back.
You can see the benchmark files here:
* <http://solarphp.com/svn/trunk/tests/Bench/Solar/Markdown.php>
* <http://solarphp.com/svn/trunk/tests/Bench/Solar/Markdown/>
Each iteration transforms the "Markdown Documentation - Syntax.text"
file from the test suite. Running on my 1.4GHz PPC Mac Mini (1 gig
RAM), results are:
* benchSolarMarkdown ran 62075 iterations in 2 minutes (517/second)
* benchPhpMarkdown ran 125904 iterations in 2 minutes (1049/second)
So the functional/procedural PHP-Markdown is a little more than twice
as fast as plugin-capable Solar_Markdown. If you transform the
source text anew on every page load, this might be an issue; if you
cache the transformed text for subsequent page loads, it's probably not.
