That's probably right... just removing centerline doesn't lead to
linebreaks, however

Hmm... that doesn't seem to do linebreaks. It shifts the part title a
bit horizontally. It also does weird things to some my *chapter* titles
(add a large space after the first word), which is configured as
    \setuphead[chapter][
        page=mychapterpagebreak,
        number=no,
        alternative=c,
        align={center, nothyphenated, verytolerant},
        style={\switchtobodyfont[16pt]},
        header=high,
        footer=chapterpage,
    ]

WTF? Very very strange!

Michael
