report-emacs-bug mode-name nit, maybe mention features ?

[John Paul Wallington]

`report-emacs-bug' will mention its buffer's `mode-name', the result
of calling `compose-mail'.  Is it better to remember the previous
`mode-name', or to omit that information ?

Also, how about including `features' in its output ?  The information
can be useful, but it isn't always (for example, if the user reports a
bug from an emacs -q --no-site-file).
