When looking at these threads, Gnus tends to generate many buffers with
crazy-long names, which tends to make using ido un-fun.

Also, I recently got the following odd-looking summary buffer by using this
feature.  Note how there was apparently a reply to my message of today
last Wednesday:

--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---


When I go to the last article and `^', the buffer changes as follows:

--8<---------------cut here---------------start------------->8---
  .  > Tuesday 12: Daniel Pfeifer * [ryppl-dev] $<> expressions in include_directories command
  .  +-> Tuesday 12: Troy Straszheim *

  .          \-> Today, 07:56: Dave Abrahams * 
--8<---------------cut here---------------end--------------->8---

The new article comes in with a negative article number, which caused me
to see some `Can't mark negative article numbers' errors; no surprise I
suppose.

Why wasn't the new article found by the original search?  I don't know,
but I think it was posted via gmane and thus had a strange In-Reply-To field
in its header:

--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

Then, in trying to reproduce the issue I did `C-u A T' on one of
today's articles from the ephemeral buffer and got

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (args-out-of-range [] 8)
  nnir-warp-to-article()
  gnus-warp-to-article()
  gnus-summary-refer-thread((4))
  call-interactively(gnus-summary-refer-thread nil nil)
--8<---------------cut here---------------end--------------->8---

which was a big surprise.
