How to terminate BCP output with specific string AND newline?
Use the ASCII codes of the characters you want to match (without the 0x prefix). 

For example to match A (char hex 41) + LineFeed (char hex 0A) do this:

-r "410A" 

This seems to be undocumented. See my blog here for more info: http://kejser.org/databases/bulk-insert-with-linux-line-endings/
