       arg.h: Handle { NULL } argv[] properly
       
       Previously, we would return argc as -1, which could cause some problems.
       This was not an issue introduced in the rewrite and is a bug present in
       the "old" arg.h as well.
       
       Thanks Isabella Parakiss for reporting this!
