+ glyph rows.
+ (append_composite_glyph): In R2L rows, prepend the glyph rather
+ than appending it.
+
+ * term.c (append_composite_glyph): In R2L rows, prepend the glyph

+ Make variable forwarding explicit rather the using special values.
+ Basically, this makes the structure of buffer-local values and object
+ forwarding explicit in the type of Lisp_Symbols rather than use

+ help us check it.
