relining code snippets

[jonathananolan]

Great package! Currently, if you have a code snippit (e.g. r data %>% distinct(User) %>% nrow() then it will put that into a new row which breaks the knitting process.

The same thing happens for lists, but in reverse - it clumps lists together onto one line and then it doesn't get recognised as a list in the knitting process.

It would be good if it could check for code snippets and not break them into a new row.
