    tmac/ps.tmac: Fallback to hyphen-minus for U+2011.
    
    Prompted by discussion with Dave Kemper in Savannah #58390.
    
    The line-breaking logic in groff does not think the fallback is a
    hyphen.
    
    Tested with:
    
        .ds a a\[u2011]
        .nr b 100 -1
        .while \n+b \*a\c
        \# "can't adjust line"
    
    and:
    
        .ds a a-
        .nr b 100 -1
        .while \n+b \*a\c
        \# "can't break line"

        Fix hyphenation bug.  The UR/UE and MT/ME macros were much too
