Instead of custom approach let's use recently introduced seq_hex_dump() helper. In one case it changes the output from 1111111122222222333333334444444455555555666666667777777788888888 to 11111111 22222222 33333333 44444444 55555555 66666666 77777777 88888888 though it seems it prints same data (by meaning) in both cases. I decide to choose to use the space divided one.
