given the markdown:
**1**
**12**
**123**
**1234**
**12345**
*1*
*12*
*123*
*1234*
*12345*
radiant produces:
<p><strong>1</strong></p>
<p><em>*12</em>*</p>
<p><strong>123</strong></p>
<p><strong>1234</strong></p>
<p><strong>12345</strong></p>
<p><em>1</em></p>
<p>*12*</p>
<p><em>123</em></p>
<p><em>1234</em></p>
<p><em>12345</em></p>
whereas the markdown dingus and textmate's convert markdown to html command produce:
<p><strong>1</strong></p>
<p><strong>12</strong></p>
<p><strong>123</strong></p>
<p><strong>1234</strong></p>
<p><strong>12345</strong></p>
<p><em>1</em></p>
<p><em>12</em></p>
<p><em>123</em></p>
<p><em>1234</em></p>
<p><em>12345</em></p>
as you can see the weird part is that only 2 digit numbers appear to be affected. I tried on two different installs, one 0.6.4 mac 10.4.10 and 0.6.2 ubuntu 7.04 with the same results on both. I also tried _ and "double underscore" (which trac would very much like to convert to underline) instead of * and ** and with the same results
