Maybe multi-line strings should remove common indent

[tv42]

Perhaps this would make sense. I can see a lot of callers wanting this; I did.

Be careful to preserve inner indentation. That is:

foo (
    # I am an embedded markdown article

    Blah blah.

        func code() {
            // code inside markdown is indented more
        }

)

Note that the # there is not a comment, it's inside the string literal (this is already current confl behavior).
