After commit 3e0c4ff (send-email: respect in-reply-to regardless of
threading, 2009-03-01) the variable $thread was only used for prompting
for an "In-Reply-To", but not for controlling whether the "In-Reply-To"
and "References" fields should be written into the email.
Thus these fields were always used beginning with the second mail and it
was not possible to produce non-threaded mails anymore until commit
15da108 ("send-email: 'References:' should only reference what is sent",
2009-04-13), which introduced a regression with the side effect to make
it possible again when --no-chain-reply-to was set.
