I'm not sure whether the rules for nested backquotes are clearly laid
out anywhere.
I think it follows logically from the syntax of one level of backquotes.
The inner backquote expands, producing a call to `cons' or `list'
which contants comma-expressions; then the outer backquote expands them.
I too found it hard to understand, and perhaps the code should be
rewritten to avoid nested backquotes, for simplicity. But it is
valid.
