Hello,

I have some more information on the cause of this bug.  It turns out that it
is an unintended consequence of the recent BVAR and KVAR changes.  The
parser used be make-docfile is very simplistic.  It assumes that when it
sees a DEFVAR_PER_BUFFER it can start looking for the documentation after 2
commas.  This assumption is no longer valid because of the added comma in
the usage of the BVAR macro.

The following patch appears to fix this problem.
