"""
|

|
|
A plugin to merge consecutive "top-level" ordered lists into one,
|
||
|
|
and also attach any intervening code blocks or blank lines to the
|
||
|
|
last list item so that the final BBCode appears as a single list
|
||
|
|
with multiple steps.
|
||
|
|
|
||
|
|
This relies on a few assumptions:
|
||
|
|
1) The only tokens between two ordered lists that should be merged
|
||
|
|
are code blocks or blank lines (not normal paragraphs).
|
||
|
|
2) We want any code block(s) right after a list item to appear in
|
||
|
|
that same bullet item.
