file_upload not using local sudo

[prune998]

I have a general problem while running fabric (and cuisine) as an unprovileged user (fabric user).

While working on the remote host, the mode_sudo (or with mode_sudo when it work... I also have troubles) work, so my user can do anything I want.

The problem comes when you want to do a local action that require to sudo.
None of the options actualy implement this.

For example, I want to sync the /home folders of my users :

userfiles = ['.bashrc', '.bash_profile', '.vimrc', '.ssh/id_rsa.pub']
user = 'foobar'
mode_sudo()
for userfile in userfiles:
file_upload('/home/'+user+'/'+userfile, '/home/'+user+'/'+userfile)

file_upload('/home/'+user+'/'+userfile, '/home/'+user+'/'+userfile)

File "/opt/fabric/.virtualenvs/fabric/lib/python2.6/site-packages/cuisine.py", line 414, in file_upload
f = file(local, 'rb')
IOError: [Errno 13] Permission denied: '/home/foobar/.bashrc'

I'm no python expert and I can't see the right way to do a such thing...
I had a similar problem whil trying to sync the users accounts... I finaly did a shadow = local('sudo cat /etc/shadow', capture = true) which is not really ellegant...

This may be more a feature request than a bug, but still...
