[Lars Ingebrigtsen]

branch: master
commit e0c9399454838444e0cc8c6c1fc1d307d9e9752b
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Add more commands to the new `C-x x' keymap
    
    * doc/emacs/killing.texi (Accumulating Text):
    * doc/emacs/display.texi (Line Truncation):
    * doc/emacs/buffers.texi (Misc Buffer): Document it.
    
    * lisp/bindings.el (ctl-x-x-map): Add new bindings for
    rename-buffer, rename-uniquely, insert-buffer and
    toggle-truncate-lines.
