I think that would be a new feature.  The --help output states:

    -C, --skip-comments       skip comment lines (starting with '#' or ';'
                                and optional whitespace)

As far as I understand the documentation, the -C, --skip-comments option
was intended to skip complete lines.

Ignoring trailing whitespace would be consistent with awk, so this seems
to be more a bug fix than a new feature.

Do you know how the "cut -F" implementations from busybox and toybox
handle trailing whitespace?

Thanks,
