  // This is a regular expression that matches reply subject lines.
  // By default, it only matches an initial "Re: ", which is the
  // standardized Latin prefix.
  //
  // However, many locales have other prefixes that are commonly used
  // too, such as Aw in Germany.  To add other prefixes, modify the first
  // parenthesized expression, such as:
  //    "^(re|aw)
  // you can add multiple values, for example:
  //    "^(re|aw|sv)
  //
  // Important:
  // - Use all lower case letters.
  // - Don't remove the 're' prefix from the list of choices.
  // - Please test the value you use inside Mutt.  A mistake here will break
  //   NeoMutt's threading behavior.  Note: the header cache can interfere with
  //   testing, so be sure to test with $header_cache unset.
