25.1.50; Bad behaviour #'generate-new-buffer-name if buffer "nil" exists |
|
Date: |
Sat, 5 Aug 2017 10:15:54 +0100 |
I start emacs:
$ emacs -Q
I type the following into *scratch*:
(progn (get-buffer-create "nil")
(generate-new-buffer-name "nil")) C-j
This gives the string "nil". This is incorrect behaviour, since "nil" is
the name of an existing buffer. On line 1080 of buffer.c, IGNORE should
be checked to be non-nil before calling Fstring_equal().
