- * The "oneline" format has several special cases:
- * - The pretty-printed commit lacks a newline at the end
- * of the buffer, but we do want to make sure that we
- * have a newline there. If the separator isn't already
- * a newline, add an extra one.
- * - unlike other log messages, the one-line format does
- * not have an empty line between entries.
+ * If use_terminator is set, add a newline at the end of the entry.
+ * Otherwise, add a diffopt.line_termination character before all
+ * entries but the first. (IOW, as a separator between entries)
