// How 'flattenTxtEntry' and 'expandTxtEntry' work.
//
// In the Route 53, TXT entries are written using quoted strings, one per line.
// Example:
// "x=foo"
// "bar=12"
//
// In Terraform, there are two differences:
// - We use a list of strings instead of separating strings with newlines.
// - Within each string, we dont' include the surrounding quotes.
// Example:
// records = ["x=foo", "bar=12"] # Instead of ["\"x=foo\", \"bar=12\""]
//
// When we pull from Route 53, `expandTxtEntry` removes the surrounding quotes;
// when we push to Route 53, `flattenTxtEntry` adds them back.
//
// One complication is that a single TXT entry can have multiple quoted strings.
// For example, here are two TXT entries, one with two quoted strings and the
// other with three.
// "x=" "foo"
// "ba" "r" "=12"
//
// DNS clients are expected to merge the quoted strings before interpreting the
// value. Since `expandTxtEntry` only removes the quotes at the end we can still
// (hackily) represent the above configuration in Terraform:
// records = ["x=\" \"foo", "ba\" \"r\" \"=12"]
//
// The primary reason to use multiple strings for an entry is that DNS (and Route
// 53) doesn't allow a quoted string to be more than 255 characters long. If you
// want a longer TXT entry, you must use multiple quoted strings.
//
// It would be nice if this Terraform automatically split strings longer than 255
// characters. For example, imagine "xxx..xxx" has 256 "x" characters.
// records = ["xxx..xxx"]
// When pushing to Route 53, this could be converted to:
// "xxx..xx" "x"
//
// This could also work when the user is already using multiple quoted strings:
// records = ["xxx.xxx\" \"yyy..yyy"]
// When pushing to Route 53, this could be converted to:
// "xxx..xx" "xyyy...y" "yy"
//
// If you want to add this feature, make sure to follow all the quoting rules in
// <https://tools.ietf.org/html/rfc1464#section-2>. If you make a mistake, people
// might end up relying on that mistake so fixing it would be a breaking change.
