That would defeat the whole point.

You missed off

     r"foo" \" r"bar";

Then how would one put a backslash at the end of a wysiwyg string?

I see now.  Do you read the input line by line?  If so, you could detect 
whether each line contains '"' or '`', and switch between r"..." and 
`...` at the beginning of the line if necessary.  You'll only need such 
messy code as the above for lines that contain both characters.

BTW I've used the search and replace technique before.  See
