[teqc] How to use "-O.sum[mary] s"

Swen,

I got part working a while back.  Then there was the fact that the
output for both "-O.sum s" and "-O.sum e" needed some major rework
after 11 years of neglect in light of GNSS constellations and RINEX
evolving so that there could easily be more 9 observables.  The
current appearance of these lines from teqc for 9 or less observables
will be like:

...
      4    L1    L2    C1    P2                              # / TYPES OF OBSERV

     48                                                      # OF SATELLITES

<etc.>

but for more than 9 observables, I'm wondering if the RINEX spec is
really going to be helpful for most users -- unless you write special
code to parse these lines.  The spec says:

*|# OF SATELLITES     | Number of satellites, for which          |     I6     |*
  |                    | observations are stored in the file      |            |
  +--------------------+------------------------------------------+------------+
*|PRN / # OF OBS      | PRN (sat.number), number of observations |3X,A1,I2,9I6|*
  |                    | for each observation type indicated      |            |
  |                    | in the "# / TYPES OF OBSERV" - record.   |            |
  |                    |                                          |            |
  |                    |   If more than 9 observation types:      |            |
  |                    |   Use continuation line(s) including     |   6X,9I6   |
  |                    |   the header label in cols. 61-80!       |            |

For more than 9 observables (e.g. on a file with L5 tracking on PRN01
and L2C on all IIR-M birds), this ends up looking like:

...
     10    L1    L2    C1    P2    S1    S2    C2    L5    C5# / TYPES OF OBSERV

Doing things like `grep PRN filename.09o | grep G01` probably won't get you
what you think you should get.
