attribution

[Bharath Bhushan <bharath.bhushan@xxxxxxxxx>]

I want to set the attribution variable such that in the initial portion 
of the reply, I can put in arbitrary headers from the original mail (at 
least From, To, Cc, Date, and Subject headers and probably more).

I read the documentation for "attribution" and for "index_format" and I 
don't see much help (Cc insertion is not possible).

I looked a bit into "reply-hook" but could not understand how I could 
achieve what I wanted using it.

Any help is appreciated.
