sudo 1.7.4

[Elan Ruusamäe]

  with sudo 1.7.4 [1], it's impossible to keep $HOME on target user and 
force target user $HOME with -H switch.

also the keep_env seem to have no effect for -H at all, i get one 
version (HOME always for target user) or the other variant (HOME always 
for source user), but no way to have both depending of using -H or not.


1. without keep_env HOME
$ sudo grep HOME /etc/sudoers
## Run X applications through sudo; HOME is used to find the
## .Xauthority file.  Note that other programs use HOME to find
#Defaults env_keep += HOME

$ sudo env | grep HOME
HOME=/root

$ sudo -H env | grep HOME
HOME=/root

$ sudo -i -H env | grep HOME
JAVA_HOME=/usr/lib/jvm/java
HOME=/root


2. with keep_env HOME
$ sudo grep HOME /etc/sudoers
## Run X applications through sudo; HOME is used to find the
## .Xauthority file.  Note that other programs use HOME to find
Defaults env_keep += HOME

$ sudo env | grep HOME
HOME=/home/glen

$ sudo -H env | grep HOME
HOME=/home/glen

$ sudo -i -H env | grep HOME
JAVA_HOME=/usr/lib/jvm/java
HOME=/home/glen


changes in code are removing initial keepenv,
plus some other changes regarding playing with $HOME and $MAIL:
