* emulation/cua-base.el: Add run-time check to catch users trying
to use older versions of CUA-mode, rather than the version
distributed with Emacs. Use autoload cookies and eval-after-load.
* startup.el (command-line): Clarify and tidy up the message
printed when there are errors in the user-init-file.
Do not encapsulate the error data; it's read by humans here.
Do not split windows when displaying the *Message* buffer.

* mail/rmail.el (rmail-insert-inbox-text): Make the pop3 mechanism
