1st only.

It should follow the spec, which is: rx clock offset is on the first line,
and then:

  |             |   If more than 12 satellites: Use continuation  |    32X,    |
  |             |   line(s)                                       | 12(A1,I2)  |

so that if a bad RINEX writer wrote the offset on the second line, teqc would
ignore it, I'm pretty sure.

The test is just `teqc RINEXname | more` and see what happens, though.
