+	_lbfsize is -_bf._size, else _lbfsize is 0
+if _flags&__SRD, _w is 0

+
+This ensures that the getc and putc macros (or inline functions) never
+try to write or read from a file that is in `read' or `write' mode.
+(Moreover, they can, and do, automatically switch from read mode to
+write mode, and back, on "r+" and "w+" files.)
+
+_lbfsize is used only to make the inline line-buffered output stream
+code as compact as possible.
+
+_ub, _up, and _ur are used when ungetc() pushes back more characters
+than fit in the current _bf, or when ungetc() pushes back a character
+that does not match the previous one in _bf.  When this happens,
+_ub._base becomes non-nil (i.e., a stream has ungetc() data iff
+_ub._base!=NULL) and _up and _ur save the current values of _p and _r.
