Yes, that seems to work too, and it saves 28 bytes.  Though since
strspn() returns the length of the initial segment it needs to be:

   size_t tmp;
   ...
   tmp = strspn(f, "-+ #0");                                         
   direc_length += tmp;                                             
   f += tmp;

They're retained in the format string which is pointed to by direc_start.
