  Fix a time calculation error in ctlstat_standard().

  ctlstat.c:	When converting a timeval to a floating point
		number in ctlstat_standard(), cast the nanoseconds
		calculation to a long double, so we don't lose
		precision.  Without the cast, we wind up with a
		time in whole seconds only.

  Fix bugs in the elapsed time calculation in ctlstat_standard()
  pointed out by bde:

  - Casting to long double isn't needed.
  - The division isn't needed, multiplication can be used.
    "When 1 nanosecond is in a floating point literal, the whole
    expression is automatically promoted correctly."
  - non-KNF indentation (1 tab) for the newly split line
  - different non-KNF indentation (5 spaces) for the previously split
    line
  - exessive parentheses around the division operation
  - bogus blank line which splits up the etime initialization
  - general verboseness from the above.
