                     16: on the standard error file
                     17: describing the indicated signal.
                     18: First the argument string
                     19: .I s
                     20: is printed, then a colon, then the name of the signal
                     21: and a new-line.
                     22: Most usefully, the argument string is the name
                     23: of the program which incurred the signal.
                     24: The signal number should be from among those found

                     31: is provided;
                     32: the signal number
                     33: can be used as an index in this table to get the
                     34: signal name without the newline.
                     35: The define NSIG defined in
