Description

When providing the input interactively via standard input, both GNU expand and GNU unexpand show the results whereas our versions don't.

Research direction

Start by reproducing the reported behavior with the expand and unexpand command entry points, piping or entering input through standard input. Compare both commands with GNU expand and unexpand; done means each local command emits transformed output interactively before stdin closes.
