There is a bug in buffer-local-value, when used in connection with
defvaralias. I believe that the ielm run below is self-explanatory.
The bug affects `C-h v" in a very confusing way. I am insufficiently
familiar with the involved C code to fix this myself.
*** Welcome to IELM *** Type (describe-mode) for help.
ELISP> (defvar aa 1)

ELISP> (make-variable-buffer-local 'aa)

ELISP> (defvaralias 'bb 'aa)

ELISP> (setq bb 2)

ELISP> bb

ELISP> aa

ELISP> (buffer-local-value 'bb (current-buffer))
1 ;; Bug: should be 2
