Better whitelisting

[joshzwiebel]

I am using whitelisting with mutmut and to the best of my knowledge you can only whitelist with #pragma: no mutate It would be nice if there was some decorator or blockquote equivalent for whitelisting more than one line at a time. In my case, I had a very long hardcoded list of strings and had many failed mutations due to the strings being mutated even though the content of the string was irrelevant in this context.

This is a duplicate of #47 where we have the discussion.

I have copied what you wrote in that PR. I have also asked a follow up question there.
