msm_sig_cmp repeats 1D, 1P, 1X ?

[ourairquality]

Could I ask if there is a reason for repeating 1D, 1P, 1X in msm_sig_cmp?

PocketSDR appears to add new entries for these are offsets 5,6,7 when they already appear at offsets 30,31,32. Might this have been for compatibility with some generator of RTCM3 streams.

Trying to sync the new codes with an RTKLib fork, and just wanting to double check if it should adopt these extra duplicate entries.

Guessing that these dups at indices 4,5,6 were meant to be for 1S, 1L 1Z (which appear to have been added in RINEX 3.05), so not dups rather a typo.
