    upstream commit
    
    Don't make parsing of authorized_keys' environment=
     option conditional on PermitUserEnv - always parse it, but only use the
     result if the option is enabled. This prevents the syntax of authorized_keys
     changing depending on which sshd_config options were enabled.
    
    bz#2329; based on patch from coladict AT gmail.com, ok dtucker@
