Subject: [PATCH] setenv: check in a more robust way that the script is being
 sourced

Sometimes a leading '-' shows up in $0 for login shells, for example
this happens when opening a shell with "sudo -i"; in these cases $0 will
look like "-bash" instead of "bash", and the comparison with $(basename
$SHELL) fails even if the script is being sourced.

Fix this by stripping the leading '-'.
