[PATCH] send-email: respect in-reply-to regardless of threading

git-send-email supports the --in-reply-to option even with
--no-thread.  However, the code that adds the relevant mail headers
was guarded by a test for --thread.

Remove the test, so that the user's choice is respected.

But it also turns out, as you can see, that git-send-email happily
ignores --in-reply-to if threading is disabled. :-(

This is the minimally intrusive fix.  It would be more consistent to
ask for the in-reply-to regardless of thread setting, but it would
also be less of a fix and more of a behaviour change.
