The plan for implementing RINEX "L2":

     * using +C2 or -O.obs with C2: +L2C_L2 and -L2C_L2 are ignored;
       the L2 (and S2, D2) are based on L2(L2C) if present, based on
       L2(P2) otherwise
     * using -C2 and -O.obs w/o C2: +L2C_L2 or -L2C_L2 takes effect,
       allowing pure L2(L2C) or pure L2(P2), respectively; default
       would continue to be -L2C_L2, i.e. RINEX L2 (and S2, D2) based
       on L2(P2)

However it was noted on the 19th (after the release) and (hopefully)
fixed yesterday that with the code released on the 19th that the desired
result for the first case of RINEX L2 would only correctly occur when
using the '+C2' option, i.e. adding RINEX C2 to the default observable
list -- and would not (necessarily) work correctly if using the '-O.obs'
option with C2 in the specified observable list.

Sorry for any inconvenience this may have caused.
