Whenever multi-paragraph list text is indented 8 or more spaces, gitiles 
renders it as a code block. Since it seems list paragraphs have to be indented 
4 spaces beyond the list item in order to be rendered along with the list item 
(<li><p></p><p></p>), this effectively limits multi-paragraph lists to only one 
level deep.

This is sort of related to Issue 73, which notes that nested lists require 4 
spaces of indent to be recognized, rather than just "indented more than the 
parent". If nested lists were recognized with only 2 spaces of indent, that 
would mitigate this problem a bit, since a list to go to 4 levels before 
hitting the automatic "8 space" handling.

Alternatively, if the automatic "8 space" handling was removed (it's arguably 
redundant with the triple-backtick notation), or at least treated relative to 
the immediate parent node, that would solve this entirely.
