Hello, In dash, set -I is a short-option alias to set -o ignoreeof.
However, bash does not have such alias, it has an undocumented set -I which switches off "invisible variables" (I don't know what that is). Standards do not mention any -I option. I propose, in the interests of keeping things less disparate, to remove set -I support from dash: make "ignoreeof" to be only an -o long option.
