I bet, itʼs a port of aforeimplied ‘gnus-treat-fill-long-lines’ and is not 
window-width-aware.  That is, if the current window is narrower than 
preconfigured fill-column, it still dumbly wraps on that column.  Let alone 
following window resizing, when the message is already displayed.

In other words, thatʼs rather a workaround, than a proper solution, which 
should rely on same display machinery, that soft-wraps lines longer than window.

Actually, depending on how you manage _system_ windows, it may make perfect 
sense to automatically shrink the frame displaying your MUA to a comfortable 
width.

Or, if resizing frames is not convenient for you (or even impossible, as on 
TTY), Iʼd suggest to use major-mode-agnostic ‘visual-fill-column-mode’ (not 
part of GNU Emacs, available on Melpa).  The following configuration bits are 
for Gnus, but you got the idea:
