    [tbl]: Fix Savannah #62471 (hrules in nroff mode).
    
    This fixes the last problem I know of that keeps man pages from freely
    using the full width of the terminal.  (You can still cause lines to
    overrun manually, of course.)
    
    * src/preproc/tbl/table.h (class table): Define new enumeration
      constant, `HAS_DATA_HRULE`, to keep track of whether a table uses a
      horizontal rule as a data row.
    * src/preproc/tbl/main.cpp (process_data): Set it when encountering
      appropriate input.
    * src/preproc/tbl/table.cpp (table::compute_overall_width): Check for it
      if the table is not already boxed, and emit output to reduce the line
      length by one in nroff mode.

    [tbl]: Regression-test Savannah #62471.
    
    * src/preproc/tbl/tests/horizontal-rules-not-drawn-too-long.sh: Do it.
    * src/preproc/tbl/tbl.am (tbl_TESTS): Run test.
    
    Test fails at this commit.
