  *   RFC822 compliant, don't SEGV and try to return as much useful

+ * Define TAL_USE_TALLOC to use libtalloc as the allocator, otherwise
+ * it will use ccan/tal (usually done on the cmdline, as tal/str will need
+ * it too).
+ *
  * Example:
- *     // Given '' outputs 'body'
- *     // Given 'From' outputs ' <from@example.com>'
- *     // Given 'To' outputs ' <to@example.com>'
+ *     // Outputs "body\n"
+ *     // Given "From" outputs <from@example.com>
+ *     // Given "To" outputs <to@example.com>
  *     char buf[] = "From: <from@example.com>\n"
  *                  "To: <to@example.com>\n\n"
