bug#11358: 24.1.50; Feature request: A way to abort emacs-client

[Harald Hanche-Olsen]

There should be a way, from within a server editing buffer, to cause
the corresponding emacs-client process to exit with a nonzero exit
status. This can then be used by the calling process as an indication
that the user has abandoned the edit.

If there is already a way to achieve this, consider this a
documentation bug: I am certainly unable to find this feature.
