    Revert "tbl(1): Document 'z' modifier as a GNU extension."
    
    This reverts commit d1f1b7247f2e4d878107af517a7f53b0d81461bc.
    
    Not a GNU extension.  Gehani documents it in his _Document Formatting
    and Typesetting on the Unix System_, Silicon Press.  I have the first
    edition, copyright 1986, which claims to document DOCUMENTER'S WORKBENCH
    (shouting capitals in original) 1.0 (1984).
    
    However, for some reason, Heirloom Doctools dropped support for it.
    
    $ cd ~/dwb
    $ printf '.TS\nLz.\nfoobar\n.TE\n' | DWBHOME=. ./bin/tbl 2>&1 \
      >/dev/null | grep . || echo no diagnostics
    no diagnostics
    $ cd ~/heirloom
    $ printf '.TS\nLz.\nfoobar\n.TE\n' | ./bin/tbl >/dev/null
    
    Input: line 2: bad table specification character
