Currently this check generates the replacement with the newline in the end. The proper way to export it to YAML is to have two \n\n instead of one.
Without this fix clients should reinterpret the replacement as "#include <utility> " instead of "#include <utility>\n"
Sorry, I don't understand how this works -- ReplacementText does not contain a \n, so lineBreakPos will be npos, and the loop below will not execute...
