I have investigated the problem a bit more and actually the cause is
not mew-summary-toggle-header-veil ― which functions well.  The "To:"
header has the form

To: Bouazza Nassim <nashasbou at example.com>, Cipolla Alessandra
	<Alessandra.CIPOLLA at example.com>, Dethise Dorian
	<dorian283 at example.com>, Alyson.DUPONT at example.com,
	Goulard Aline <Aline.GOULARD at example.com>, Jottrand Blaise
	<Blaise.JOTTRAND at example.com>, Pirenne Pauline
	<Pauline.PIRENNE at example.com>, Simons Charline
	<Charline.SIMONS at example.com>, Wautelet Benoit
	<benoitwau at example.com>, Wyckhuys Adrien
	<Adrien.WYCKHUYS at example.com>, Zaoui Abdenasser
	<Abdenasser.ZAOUI at example.com>, Dawant Samuel
	<samrenfou at example.com>, 
	<Aurelie.DEPOORTERE at example.com>, Evrard Laurent
	<Laurent.EVRARD at example.com>, Gamrath Sebastien
	<Sebastien.GAMRATH at example.com>, Helenus Angelo
	<Angelo.HELENUS at example.com>, Iovine Nadege
	<Nadege.IOVINE at example.com>, Lanssens Benjamin
	<Benjamin.LANSSENS at example.com>, Mercier Morgan
	<Morgan.MERCIER at example.com>, Piette Antoine
	<Antoine.PIETTE2 at example.com>, Blondiau Laurent
	<Laurent.BLONDIAU at example.com>

(the message was prepared with mew, each address was originally on a
single line) and, after running 

  (mew-header-decode-region "To:" beg end)

it becomes

To: Bouazza Nassim <nashasbou at example.com>, Cipolla Alessandra <Alessandra.CIPOLLA at example.com>, Dethise Dorian <dorian283 at example.com>, Alyson.DUPONT at example.com,
	Goulard Aline <Aline.GOULARD at example.com>, Jottrand Blaise <Blaise.JOTTRAND at example.com>, Pirenne Pauline <Pauline.PIRENNE at example.com>, Simons Charline <Charline.SIMONS at example.com>, Wautelet Benoit <benoitwau at example.com>, Wyckhuys Adrien <Adrien.WYCKHUYS at example.com>, Zaoui Abdenasser <Abdenasser.ZAOUI at example.com>, Dawant Samuel <samrenfou at example.com>,
	<Aurelie.DEPOORTERE at example.com>, Evrard Laurent <Laurent.EVRARD at example.com>, Gamrath Sebastien <Sebastien.GAMRATH at example.com>, Helenus Angelo <Angelo.HELENUS at example.com>, Iovine Nadege <Nadege.IOVINE at example.com>, Lanssens Benjamin <Benjamin.LANSSENS at example.com>, Mercier Morgan <Morgan.MERCIER at example.com>, Piette Antoine <Antoine.PIETTE2 at example.com>, Blondiau Laurent <Laurent.BLONDIAU at example.com>

(the new lines being created iff the address starts the line).  The
problem is that this is composed of long lines of addresses and
mew-summary-toggle-header-veil counts lines and not addresses.  Since
this is difficult to read anyway, I believe addresses lines (To:,
Cc:,...) should be "reorganized" so that lines contain no more
addresses than 78 chars can display (unless the address itself is too
long).

Since mew-summary-toggle-header-veil makes *lines* invisible, I was
under the impression that it had no effect (the invisible lines were
below the portion of the buffer that was displayed).

What is the best way to deal with this?

Best,
C.
