Actually, you don't need to do that, unless you want to take
benefit from what LAYOUT does without having to do it by yourself.
Since you are asking to avoid what the TEXT style does (i.e.
TRIM/LINES on your text), and you already have your faces built,
using layout is just overkill.
As I said earlier, you just need to set the TEXT facet to your
text, as in:
face/text: "Multiline^/text"
View does *not* remove that newline by default. Is the TEXT style
that does when used in VID without using AS-IS.

[

if none? text [text: copy ""]
change font/colors font/color
if :action [feel: svvf/hot saved-area: true]
data: size
if any [none? size size/x < 0 size/y < 0] [
state: max 1x1 pane-size * 9 / 10 - offset - para/margin
if none? size [size: state]
if size/x < 0 [size/x: state/x]
if size/y < 0 [size/y: state/y]
size: size-text self
all [
para para/origin size: size + para/origin
para/margin size: size + para/margin
]
]
if all [data data/y < 0] [size/x: data/x]
data: none
]
Notice the first line:
if all [not flag-face? self as-is string? text] [trim/lines text]
HTH,
Gabriele.
