config: write existing lines as-is when rewriting When updating a configuration file, we want to copy the old data from the file to preserve comments and funny whitespace, instead of writing it in some "canonical" format. Thus, we keep a pointer to the start of the line and the line length to preserve these things we don't care to rewrite.
