lisp/ChangeLog addition:
2015-04-04 Aidan Kehoe <kehoea@parhasard.net>
* gutter-items.el (append-progress-feedback):
* gutter-items.el (abort-progress-feedback):
Correct comments in both these functions, it's the progress stack
being adjusted, not the message stack.
* simple.el (message-stack):
Describe my recent change in the structure of this.
* simple.el (current-message):
Adjust the implementation of this to always return the string
displayed.
