-
- CURRENT-ALIST-ELEMENT is a pointer to an element of BUFFER's

- variable. Or it can be a pointer to the

- if BUFFER does not have an element in its alist for this
- variable (that is, if BUFFER sees the default value of this

-
- If we want to examine or set the value and BUFFER is current,
- we just examine or set REALVALUE. If BUFFER is not current, we
- store the current REALVALUE value into CURRENT-ALIST-ELEMENT,
- then find the appropriate alist element for the buffer now
- current and set up CURRENT-ALIST-ELEMENT. Then we set
- REALVALUE out of that element, and store into BUFFER.
-
- If we are setting the variable and the current buffer does not
- have an alist entry for this variable, an alist entry is
- created.
-
- Note that REALVALUE can be a forwarding pointer. Each time it
- is examined or set, forwarding must be done. Each time we
- switch buffers, buffer-local variables which forward into C
- variables are swapped immediately, so the C code can assume
- that they are always up to date.
-
- Lisp_Misc_Buffer_Local_Value and Lisp_Misc_Some_Buffer_Local_Value

- merely setting the variable while some buffer is current
- does not cause that buffer to have its own local value of this variable.
