942 The actual contents resemble a cons cell which starts a list like this:
943 (REALVALUE BUFFER CURRENT-ALIST-ELEMENT . DEFAULT-VALUE).
944
945 The cons-like structure is for historical reasons; it might be better
946 to just put these elements into the struct, now.
947
948 BUFFER is the last buffer for which this symbol's value was
949 made up to date.
950
951 CURRENT-ALIST-ELEMENT is a pointer to an element of BUFFER's
952 local_var_alist, that being the element whose car is this
953 variable. Or it can be a pointer to the
954 (CURRENT-ALIST-ELEMENT . DEFAULT-VALUE),
955 if BUFFER does not have an element in its alist for this
956 variable (that is, if BUFFER sees the default value of this
957 variable).
958
959 If we want to examine or set the value and BUFFER is current,
960 we just examine or set REALVALUE. If BUFFER is not current, we
961 store the current REALVALUE value into CURRENT-ALIST-ELEMENT,
962 then find the appropriate alist element for the buffer now
963 current and set up CURRENT-ALIST-ELEMENT. Then we set
964 REALVALUE out of that element, and store into BUFFER.
965
966 If we are setting the variable and the current buffer does not
967 have an alist entry for this variable, an alist entry is
968 created.
969
970 Note that REALVALUE can be a forwarding pointer. Each time it
971 is examined or set, forwarding must be done. Each time we
972 switch buffers, buffer-local variables which forward into C
973 variables are swapped immediately, so the C code can assume
974 that they are always up to date.
975
976 Lisp_Misc_Buffer_Local_Value and Lisp_Misc_Some_Buffer_Local_Value
977 use the same substructure. The difference is that with the latter,
978 merely setting the variable while some buffer is current
979 does not cause that buffer to have its own local value of this variable.
