_M_k_d_i_r creates specified directories in mode 777. Standard entries, `.', for the directory itself, and `..' for its parent, are made automatically.
_M_k_d_i_r requires write permission in the parent directory.
_M_k_d_i_r returns exit code 0 if all directories were success- fully made. Otherwise it prints a diagnostic and returns nonzero.
