env_delete += "LC_ALL" is ignored

[Gioele Barabucci]

sudo 1.6.9p17 ignores env_delete += "LC_something" and env_delete = "LC_something" in /etc/sudoers

$ sudo cat /etc/sudoers | grep Defaults
# Defaults
Defaults !lecture,tty_tickets,!fqdn
Defaults env_delete += "LC_ALL LC_NAME"

$ export LC_ALL='foobar'

$ sudo -i
# set | grep LC_ALL
LC_ALL=foobar

This is a comment I received from the author:

  env_delete is only used when env_reset is not enabled.
  Since env_reset is the default now, you probably want to
  remove "LC_*" from env_check.

At least the manpage should be updated to inform that env_delete is ignored when env_reset is set (like it is in Ubuntu).

The requested documentation change was made according to the upstream ticket and I was able to verify this in trusty.

Closing as fixed.
