[PATCH] Emacs: Add variable to toggle message indentation in a thread

[Felix Geller]

Hi Dmitry,

thank you for the comments. I included an updated patch that also
includes Daniel's comment regarding the default value. 

I didn't change the "when" though--not because of personal reasons
;)--but because it is used for determining indentation of multi-parts.


Cheers,
Felix
