org.el: Improve accuracy of message
* lisp/org.el (org-remove-file): Reword success message.
Before this change, when `org-remove-file' succeeded in removing a
file from `org-agenda-files', it would display this unduly alarming
message to the user: "Removed file: foo.org". This made it seem as
though the file itself were removed from the filesystem, rather than
simply being delisted from `org-agenda-files'.
After this change, the message "Removed from Org Agenda list: foo.org"
is displayed instead, so the user will experience only the normal
level of panic involved in using Org Mode, not the increased panic
that results from thinking a file has been removed when it hasn't.
