Comment (by yawning):

 A single trailing dot probably should be allowed, though Firefox
 apparently has some odd behavior here (Eg:
 https://bugzilla.mozilla.org/show_bug.cgi?id=134402 also something with
 cookies, something with the password manager, etc.).

 The dot started off as a BSD-ism to indicate to the resolver that the
 domain is absolute, `FQDN` isn't actually formally defined in the RFCs in
 a consistent manner (comment 28 in the mozilla bug has a summary), but
 dealing with it is easy.

 Even among the tools shipped with BIND, `dig` and `nslookup` both deal
 with a trailing dot correctly while `host` spits back an error, which is
 amusing since I would have hoped they'd get it correct.

 I'll fix this when I have a moment.
