Sorry for my slow review on this - need to figure out whether I'm happy with how we're iterating over the characters of a source line. |

There was a problem hiding this comment.
This could also be rewritten using str::rfind, but because we have to find the first trailing non-whitespace character, we would have to find the char lengt of the character to adjust, which makes it not much clearer than the curren solution.
Suggested change

This should resolve #261.
Is this just okay like this, or should this be configurable?
