[Qemu-trivial] [PATCH trivial] vl: Avoid to close stdout after finish 'w


From: Chen Gang
Subject: [Qemu-trivial] [PATCH trivial] vl: Avoid to close stdout after finish 'writeconfig' option
Date: Sun, 20 Apr 2014 20:05:13 +0800
User-agent: Mozilla/5.0 (X11; Linux x86_64; rv:17.0) Gecko/20130625 Thunderbird/17.0.7

After finish 'writeconfig' to stdout (with '-'), we want to copy/past
the related information mannually, not for redirection ('readconfig'
does not support '-').

So we can not close the stdout, or next options which may use stdout
will not be displayed.
