-strtok_r().  strtok_r() initially takes a char * pointing to the start of
-a line, and then NULL to indicate continued processing.  strtok_r() does
-not provide a mechanism for getting pointer to the unprocessed portion
-of a line.  Alias processing is done part way through a line after
-strtok_r().  This routine relies on further calls to strtok_r(), passing
-NULL as the first parameter, returning alias names from the line. */
