  Log Message:
  -----------
  Initialize a pointer in split_init_cmd() to avoid gcc warnings

gcc -Wall warns about uninitialized variables (-Wmaybe-uninitialized), and
-Werror makes it fatal. This change allows the build to succeed by NULL'ifying
the pointer passed to strtok_r().

Note that strtok_r(3) anyway ignores a non-NULL arg3 pointer on the 1st call
with non-NULL arg1 string.
