 Replying to [comment:3 nickm]:

 that calling hex_str() invalidates its return value.

 Added a sentence to the documentation.

 > In extrainfo_dump_to_string:

 > This should be unneeded, since tor_snprintf always nul-terminates.
 > +        write_stats_to_extrainfo = 0;
 > Why?  The right response on tor_snprintf() failing here is probably just
 to call the whole extrainfo a failure.

 Okay. I took this code out of the if block. If writing the geoip-db-digest
 line fails, writing the extra-info descriptor fails, too.

 > Other than that looks fine.

 Great! Thanks for the feedback. Please find the updated branch
 enhancement1883 in my public repository.
