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...
