    tmac/doc.tmac-u: Punctuation handling of .Lk fixed
    
    The implementation of the groff_mdoc(7) .Lk (hyperlink) macro
    contains code to make sure that the second argument is not
    punctuation before treating it as a link text, but the test
    can never lead to the result "punctuation" because the
    initialization of the global variable doc-width was missing
    before the call to doc-get-arg-type.  Consequently, even "."
    was not recognized as punctuation.
