    doc/meref.me: Fix content nit.
    
    The -me Reference Manual is fairly scrupulous about documenting the
    default values of its registers, but $v and $V are two exceptions.
    [This commit] documents the default values for these (both 120).
    
        $ groff -me <<<'.tm \n($v \n($V'
        120 120
    
    There is also what I feel is an oddity in the nearby wording: "The line
    spacing as a percentage of the point size expressed in units is stored
    in \n($v."  I'm not sure what the phrase "expressed in units" is
    supposed to communicate; it's not clear whether it modifies "line
    spacing" or "point size," and neither really makes sense, even mentally
    adding the presumably intended "basic" before "units."
    
        $v is a percentage; if it meaningfully has a unit at all, that unit
        is %.
    
        In what units the point size is expressed or stored is irrelevant to
        a percentage: 120% of the point size is not dependent on the units
        expressing that point size.
    
    Thus this patch removes the phrase entirely.  If someone has a better
    idea what that phrase is trying to say, it could instead be reworded to
    say it more clearly.
    
    Fixes <https://savannah.gnu.org/bugs/index.php?61314>.
    
    [It would be nice to say "type size" instead of "point size", but
    consistent usage would demand a much more intrusive change.  --GBR]
