When using html pre/code tags to wrap github's fenced code block syntax,
showdown would parsed them instead of treating them like plain code.
Closes#229
The spec states that you can be lazy and only put the `>` before the first line of a hard-wrapped paragraph.
It also states that blocquotes can contain any other md element inside.
This means headings and horizontal rules should be included in the blockquote but, right now, are treated as
independent entities
Closes#191
Fix ghCodeBlocks not being correctly parsed inside lists. Also, as a side
effect, fixes issues with consecutive lists and extra paragraphs being
added into lists.
Closes#142, Closes#183, Closes#184
Consecutive lists we're previously being condensed into one unique list, with odd paragraph output.
This fix correctly splits lists, but does not change the weird paragraph output
closes#142
