This documentation change fixes the description of vnc_password in
qemu.conf to fit the behaviour introduced in commit
ab952024f42726a291d2c0ceda10071b88da7533 which treats a non-existent VNC
password and an empty string password in the same way.

# The default VNC password. Only 8 letters are significant for
# VNC passwords. This parameter is only used if the per-domain
# XML config does not already provide a password. To allow
-# access without passwords, leave this commented out. An empty
-# string will still enable passwords, but be rejected by QEMU
-# effectively preventing any use of VNC. Obviously change this
