<bar> is a sentance that doesn't render correctly
The only way to fix this right now is to double up the backticks on the first instance (because of the trailing single quote).
It's close to impossible to fix this until we switch to an inline parser. There's just no way the current regex-based parsing can detect these scenarios without lots and lots of passes over the text. We basically have tricks in place to handle the most blatant situations, but that's really just to tide us over until we can parse in a more intelligent way. Hence the relationship to #61.
