    man/groff.7.man: Fix rendering nit.
    
    The documentation of the '\s±(N', '\s±[N]', and "\s±'N'" syntax forms
    was rendering the '±' in the bold used to indicate literal input instead
    of the italics used for parametric input.  This is because those syntax
    forms are unique to \s and the page-private macros that the page author
    wrote in an apparent effort to "semantically lift" the page contents
    were inadequate to express them.
    
    My preference would be to ditch the page-private macros altogether but
    that is a larger effort.
    
    Note that in PostScript/PDF output, an italicized '±' does not appear in
    italics.  I assume that is because it is drawn from the "symbol font" S,
    which lacks styling.  This is not a regression; none of the existing '±'
    glyphs in italic context render italicized or slanted either.  The
    output now looks correct on terminals, however.
