<a b c>
is the same as
Q :single :words < a b c >
Note that :single means it acts like single quotes.
Single quotes don't do anything to convert '\n' into anything other than a
literal '\n'.
If you want that to be converted to a linefeed you need to use double quote
semantics (or at least turn on :backslash).
Q :double :words < a\n b\n c >
Of course that also doesn't do what you want because a linefeed character
is also whitespace, so it gets removed along with the rest of the
whitespace.
What you want to do use is :quotewords and "".
Q :quotewords < "a\n" "b\n" c >
The short way to write that is
<< "a\n" "b\n" c >>
Although if you are going to append a newline to every element I would
consider writing it this way:
< a b c > X~ "\n"
or
< a b c > »~» "\n"
