Everything in apps includes apps.h, because that one declares apps internal library routines. However, progs.h doesn't declare library routines, but rather the main commands and their options, and there's no reason why the library modules should include it. So, remove the inclusion of progs.h from apps.h and add that inclusion in all command source files.
