This I cannot explain. It doesn't look right at all. However if you define
the source string differently it works:
trim/auto copy rejoin [" one two" newline " three four " ]
== "one two^/three four "
> >> a3: trim/with "^/" copy a2

You got your parameters in the wrong order. Should be:
>> a3: trim/with copy a2 "^/"
== "one two three four "

Is correct
> >> a4: trim/with "two" copy a3
> == ""
Again, the order of your parameters is wrong. Do this instead:
>> a4: trim/with copy a3 "two"
== "nehreefur"

No. Trim/with interprets the supplied string value as a set of characters
that must be removed from the source string. It does not remove sub-strings.
