report-emacs-bug, flyspell

[David Reitter <david.reitter@gmail.com>]

When enabling flyspell in a buffer created by M-x report-emacs-bug, or  
when flyspell is generally enabled for all text modes with (add-hook  
'text-mode-hook 'flyspell-mode), an error from within post-command- 
hook is thrown: `message-signature-separator' is void.

The reason for that is that `mail-mode-flyspell-verify' wrongly  
assumes that `message-signature-separator' is defined.  `report-emacs- 
bug' enables mail mode, but does not load `message'.

A simple fix follows.
