Updating src/contrib/binutils

Hi David,

because you are the maintainer of src/contrib/binutils, I first want to ask 
you before I start to update src/contrib/binutils. I've read the README's 
you've placed there, but 2 questions remain:

1) How can I create a patch using a cvs-checkout when I do not have
    write permissions to the repository? This is no request for a commit
    bit (to much accountability), more a technical request.
    Do I need to use cvsup from ports to get a copy of the cvs server
    and checkout against my local copy?
2) Is it ok to do it on a FreeBSD7-Stable, as long no change between
    the RELENG7 branch and the HEAD prevents merge? Or is it mandatory
    to test it with -CURRENT?
    I ask, because -CURRENT maybe unstable by definition, and I don't
    want to search for errors in my work come in by experimental code.
    I have no problem, when a first patch exists, to test it on -CURRENT,
    but it should be the 2nd step (for me).

Best regards,
Jens
