Subject: 24.2; Completion for "C-x b" does not include current buffer
Date: Sat, 17 Nov 2012 15:44:13 +0000

In older Emacs versions (*), to switch buffer, I could type "C-x b",
followed by a unique prefix of the desired buffer's name, then "TAB
RET". This routine no longer works. Specifically, the completion fails
when the desired buffer is already the current buffer. So before I can
switch, I first have to work out which window is selected and whether
its buffer is the one I want.

In my opinion this was a bad decision, and I think we should go back
to using "B" as the interactive spec for switch-to-buffer. Others
might disagree, so would it be possible to add a custom variable to
control whether the current buffer is included in the list of completions?

(*) (I think the behaviour changed on the trunk in
revisions 86915 and 86916, in April 2008.)
