        !            14: .SH DESCRIPTION
        !            15: .I Colcrt
        !            16: provides virtual half-line and reverse line feed sequences
        !            17: for terminals without such capability, and on which overstriking
        !            18: is destructive.
        !            19: Half-line characters and underlining (changed to dashing `\-')
        !            20: are placed on new lines in between the normal output lines.
        !            21: .PP
        !            22: The optional
        !            23: .B \- 
        !            24: suppresses all underlining.
        !            25: It is especially useful for previewing
        !            26: .I allboxed
        !            27: tables from
        !            28: .IR  tbl (1).

        !            30: The option
        !            31: .B \-2
        !            32: causes all half-lines to be printed, effectively double spacing the output.
        !            33: Normally, a minimal space output format is used which will suppress empty
        !            34: lines.
        !            35: The program never suppresses two consecutive empty lines, however.
        !            36: The
        !            37: .B \-2
        !            38: option is useful for sending output to the line printer when the output
        !            39: contains superscripts and subscripts which would otherwise be invisible.
        !            40: .PP
        !            41: A typical use of

        !            54: option so that
        !            55: a true underline character would show; if we did this, however,
