Hi,all.
According to changelog, there is a shell's new feature about non-interactive
mode.
It says non-interactive mode shells exit if -u is enabled and an attempt in
made to use an unset variable with the % or # expansions, the '//', '^', or ','
expansion, or the parameter length expansion.
"if -u is enabled", does it mean "shopt -u interactive_comments" or anything
else?
