Do you see those weird lines?
(Also test without -nw too.)

That's normal: faces straddle the newline.  In this case, it's the
underline face, but you will see the same if you use a face with a
non-default background color.

Well then something else needs to be fixed.

All that hard work to make man pages look good,

but then this obvious error connecting unrelated items,

just because they are in the same face or something.

You must admit it looks terrible.

From looking at this, the man page formatting is ok, but there is a
problem with the buttons added to allow following references.

The first overlay button added by `Man-highlight-references0' uses a
start position in the middle of a subsection heading in the "SEE ALSO"
section, so something is not right with the regexps that locate these
references.

Thanks, I fixed that one (and also another problem with handling
references to manpages divided between two lines).  The more general
problem, however, with the underline face straddling a newline, cannot
be helped.
