Given we use terminal emulators on pixel-based devices and our choice
of font, I still see a significant difference with

    $ troff -Tutf8 <<<'Re-sort with \-u.' | grotty | grep .
    Re‐sort with −u.

The hyphen is narrower so doesn't crash into the following rune.  It also
sits at a different height.  Whereas the option's dash is heavier and
more noticeable, as it should be given its significance.

Cheers, Ralph.
