Hex output in mosquitto_sub needs leading zeros

[skiizo]

With mosquitto_sub and hex output format, if the message contains byte values less than 16, the leading zeros are not printed.

I believe this is the spot in the code:

mosquitto/client/sub_client_output.c

Line 88 in 44135bc

fprintf(stdout, "%x", payload[i]);

Perhaps just using "%02x" there would do it. As well as "%02X" a few lines down for the upper-case hex.

Agreed! I've fixed this on the fixes branch. Thanks for the report.
