Bugfix: The IKI variables that expand reserved words should expand into multiple parameters.

Reserved words, such as the ones regarding the --mode parameter, have multiple values then these should themselves expand into multiple values.
Wrapping quotes can be added to prevent this behavior.

There may be previous issues that intentionally added this (and then possibly as a bugfix).
The previous behavior of expanding multi-valued reserved words into a single parameter value when not using quotes is now considered a bug.
