Extra space in X-Draft-From field when drafting a messgage

[Cheng Gao]

When drafting a message, a X-Drafr-From header is inserted
automatically. But there is a extra space in the field as

X-Draft-From: ("nntp+news.gnus.org:gnu.emacs.gnus" )
                                                  \ here  

I just wanna know if it's a feature or a bug.

Another question:
How to add a Gcc field with value as the group I am drafting from with
posting style? I know it can be done with gnus-parameters as
(gcc-self . t)

I am just curious if it can be dont via posting style.

TIA,

CG
