Okay, I understand.  "Unintended behaviour" instead of "bug" ;-) but
behaviour that I can accept, especially as the easy solution is to
simply enclose the equation in a latex block:

--8<---------------cut here---------------start------------->8---
* equation with leading minus sign
  The following equation
#+begin_latex
  \begin{equation}
  \label{eq:test}
  y = 3 x
  - 5
  + 4
  \end{equation}
#+end_latex
--8<---------------cut here---------------end--------------->8---

This works just fine and is probably for the best in any case.  Using a
latex block allows for latex specific editing (C-c ').  Should have done
this in the first place!

Sorry for the noise!

Thanks,
eric
