104
 * _ub, _up, and _ur are used when ungetc() pushes back more characters
105
 * than fit in the current _bf, or when ungetc() pushes back a character
106
 * that does not match the previous one in _bf.  When this happens,
107

108
 * _ub._base!=NULL) and _up and _ur save the current values of _p and _r.
