Update message-stack to reflect START and END supplied to #'append-message
lisp/ChangeLog addition:
2015-03-11 Aidan Kehoe <kehoea@parhasard.net>
Correct #'clear-message and friends so the START and END supplied
to #'append-message are reflected when restoring messages from the
message stack.
* simple.el (remove-message-hook):
Update this to reflect the START and END keyword arguments.
* simple.el (log-message):
Update this to take START and END keyword arguments.
* simple.el (clear-message):
Update this to reflect a changed `message-stack' alist structure.
* simple.el (remove-message):
Update this to reflect a changed `message-stack' alist structure;
don't do `with-trapping-errors' and resignal use
#'call-with-condition-handler directly instead, for better
backtraces and easier debugging.
* simple.el (append-message):
Update this to reflect a changed message-stack structure.
