>Description:
According to the CHANGES file (#432) in the sudo source code "env_reset" is normally default!

sudo -V shows that there is no "Reset the environment to a default set of variables",
but only "Ignore '.' in $PATH".

This is NOT sufficient and will fail in following test case (see "How to repeat").


>How-To-Repeat:
% echo 'echo BULLSHIT' > date
% chmod +x date
% date
% export PATH=.:$PATH
% date
% sudo date
% sudo sh
# date


>Fix:
Use the default "env_reset" instead of "ignore_dot"!
