local function to return string value when determining user name

Comment 7 Clark Williams 2016-09-20 14:04:33 UTC
The above patch adds the local function get_user_name() which handles empty environment variables SUDO_USER and USER. This patch modifies the original patch and will be available in the next build of rteval (2.12).
