Aha yup. I just discovered some days ago bash actualy use something
called "dynamic scopes". In short, if a var is define outside of the
scope, bash update this variable value. Except if "local" is used ofc.

Is it possible to add "local IFS" where needed ? This will make the
_append_to_compreply IFS useless right ?
