Oh, OK.

I put the following into my .dir-locals.el:

(fundamental-mode . ((indent-tabs-mode . nil)))

, and then ran the following command "in" the current directory
containing the .dir-locals.el:

  M-: (with-temp-buffer (message "indent-tabs-mode: %s.  major-mode: %s" 
indent-tabs-mode major-mode))

Displayed was:

  "indent-tabs-mode: t.  major-mode: fundamental-mode"

.  So it would appear that the temporary buffer, although ostensibly in
fundamental mode, isn't picking up the .dir-local.el variables.  In fact,
it would appear, from looking at the code, that `fundamental-mode' doesn't
get called.  It isn't clear to me where `major-mode', which presumably is
set to binary zeros when the buffer structure gets allocated, gets set to

Maybe we just don't need to worry about this - it appears to do the Right
