* (Frename_buffer): When the current buffer is already named NAME, don'tRoland McGrath1993-11-201-1/+5
| | | | | | | short-circuit and just return unless UNIQUE is nil. This makes passing UNIQUE=t equivalent to (rename-buffer (generate-new-buffer-name NAME)). This is useful way to rename the buffer automatically so you can create another with the original name.
* Undo last change. SPC feeping at you is too annoying.Roland McGrath1993-11-201-1/+1
