signature verification data

[auto15963931 at hushmail.com]

When an encrypted file sent to me is both encrypted and signed, 
when I use a command like this:

gpg -o file-out -d file-in


I can see the signature verification data appear as standard 
output, in the terminal, while the file-out contents are separated 
from it.  Is there a way to have the signature verification data 
appended to the file-out text message itself or possibly some other 
way of preserving this verification data and keeping them together? 
I am referring to the command line interface, but I noticed that 
GPA also keeps them separated. Thanks.
