json files in the level 1 directory are used for ArchStd events (see
preprocess_arch_std_files), as such they shouldn't be warned about.

We could get more elaborate and add the same first debug print in 
process_one_file() to preprocess_arch_std_file() to give the allusion 
that they are preprocessed, and change the logic not print that for arch 
std files (in process_one_file()). But not sure it's worth it.

Or else we could also just omit any print here for archstd files here.

But I suppose what you are doing is ok...

Thanks,
John
