hmmm, same program/command in different directories with different
behaviour...
I guess the simplest thing is to let the people with sudo access adjust
their own PATH in ~/.profile or the like.

But, to do as you suggest, only alter the path if the sudo command were
used, would require a sudo function...

something like:
sudo() {
    local oldath=${PATH}
    PATH="/usr/local/sbin:/usr/sbin:/sbin:${PATH}"
    /usr/bin/sudo $@
    local retval=$?
    PATH=${oldpath}
    return ${retval}
}

Interesting idea...
