IOW, do it more like this?

>> -test_three_modes () {

	"$@" <input >actual

i.e. treat each parameter as separate things without further getting
split at $IFS and ...

>> +test_three_modes () {
>> +	run_three_modes "test-tool reach $1"

	run_three_modes test-tool reach "$1"

... make sure there three things are sent as separate, by quoting
"$1" inside dq.

I think that makes sense.
