+This can be the symbol of a line-number-mode that should always be
+enabled for the duration of `goto-line-preview`. This is useful if you
+are in a buffer that is not showing line numbers but would like to see
+then when you invoke `goto-line-preview`.
+
+Modes known to work are `display-line-numbers-mode`, `linum-mode`,
+and `nlinum-mode`. The default value is `nil`.
