I have included some source code (actually the contents of a config file) in a post, something like:
```
# this is a comment
setting = 1
```
which displays correctly here and on my hosted blog:
# this is a comment
setting = 1
But in the timeline/post pages, the # is interpreted as a markdown heading, thus displays as:
```
this is a comment
setting = 1
```
(so it says it’s a comment, but actually is shown as a heading)
Presumably markdown parsing should be suspended within code sections, in part to allow for markdown to be included as a code block within a post?
