Inserting newlines is not the important part of this variable's
effect.  The important part is filling the text, and shr does that
with fixed-pitch and variable-pitch fonts alike.  The NEWS entry
should describe this important part.

I evidently fail to explain myself, so let me just propose an entry
as I envisioned it:

 *** EWW now enables 'visual-wrap-prefix-mode' when 'shr-fill-text' is nil.
 By default, 'shr-fill-text' is t, and EWW fills the text according to
 the width of the window.  If you customize 'shr-fill-text' to nil,
 EWW will now automatically turn on 'visual-wrap-prefix-mode' in
 addition to 'visual-line-mode', so that long lines are wrapped at
 word boundaries near window edge and the continuation lines are
 indented using prefixes computed from surrounding context.
