first argument doesn't start with a '-' and ends in 't', the 't' only gets converted to a 'T' (for listing processes on the current tty) if it doesn't contain any other command line option characters that take an argument. Problem noticed by ITOH Yasufumi on tech-userlevel. If the 'start' format was the last column, the width wouldn't be set and started() output a zero length string instead of a string the right length - fix header width calculations so the the last column is handled the same all others. This only showed up for 'start' because started() knew that the column header is the same width and the field itself... Update copyrights.
