Feel free to do so. I just felt that changing the type from str to
List(str) would be non-trivial and I couldn't immediately figure out
whether that works as intended. It would have the additional benefit of
also removing the indentation. When removing the first line you get the
very same problem with indentation rather than newline. Diff these
against one another:

"line1\n line2\n line3"
"line1\n line2"
"line2\n line3"

So yeah, we need a better solution here.
