Have _eend() assume 80 columns in the absence of a smart terminal
In cases where the value of genfun_tty is lower than 2, it is implied
that the standard output refers either to a terminal insufficiently
capable of handling ECMA-48 CSI sequences or to a resource that is not a
terminal. Use <space> characters to indent the indicator to the extent
that the last character falls on the 80th column. Previously, the
indicator was indented by only one <space>.
