It turns out that the handling of nested backquotes was simply not working.
The reader's treatment worked (although IIRC it only works since Emacs-21),
but the backquote expansion was flawed.  As for the above bug it comes from
an incorrect treatment of the new backquote style (and its nesting) in the
printer (used by the byte-compiler, hence the above problem only appeared
when using log-view.elc rather than log-view.el which is why it worked fine
when I wrote the code).

I believe I've now fixed both problems in the 22 branch (should be merged into
the trunk in a couple days).
