[Message part 1 (text/plain, inline)]

I forgot to update the documentation in buffers.texi:

[0001-Fix-handling-of-not-by-buffer-match-p.patch (text/x-patch, inline)]

Subject: [PATCH] ; Fix handling of 'not' by 'buffer-match-p'

* lisp/subr.el (buffer-match-p): Look up the cadr instead of the cdr
for the negation in 'not'.
* doc/lispref/buffers.texi (Buffer List): Update documentation.
