    ace: avoid compiler warnings
    
    Skip compiler warnings about 'fields' or 'field_name' being used uninitialized.
    
      fr-command-ace.c: In function ‘process_line’:
      fr-command-ace.c:135:20: warning: ‘field_name’ may be used uninitialized in this function 
[-Wmaybe-uninitialized]
        if (field_name[0] != '/') {
                          ^
      fr-command-ace.c:122:40: warning: ‘fields’ may be used uninitialized in this function 
[-Wmaybe-uninitialized]
        if ((fields == NULL) || (fields[0] == NULL) || (g_strv_length (fields) < 5))
                                           ^
