Option -E is different for "less" and "more".
for "less" - causes to automatically exit the first time it reaches
end-of-file.
for "more" - option -E and -e is equivalent and causes to automatically
exit the second time it reaches end-of-file.
Behaviour "exit the first time it reaches end-of-file" set on default for
"more", therefore was removed scan_option("-E").
This patch return the old behaviour:
