It does look much cleaner using 'copy-marker'. Thanks a lot for the review!

[O] [PATCH] org-capture: cannot abort cleanly after inserting at end of buffer

2017-11-02 Thread Xavier Martinez-Hidalgo
Hi,

After the following steps:

- Start a capture.
- Move to end of capture buffer (M->).
- Type some text.
- Abort capture (C-c C-k).

the capture is aborted but its contents are not removed from the
target buffer and the following message is shown:

  "Capture process aborted, but target buffer could not be cleaned up
  correctly"

I am a attaching a patch that adds a test case showing up the problem
and includes a proposed fix (setting the capture kill end marker
insertion type).

I am not sure whether the fix might affect something else.  Does the
fix makes sense?

Subject: [PATCH] org-capture: Fix aborting after inserting text at end of
 buffer

* lisp/org-capture.el (org-capture-mark-kill-region): Set end marker
  insertion type so that it advances when inserting text at the end of
  the capture buffer.

* testing/lisp/test-org-capture.el (test-org-capture/insert-at-end-abort):
  Add test case.

Inserting text at the end of the capture buffer does not advance the
end kill marker.  This causes the narrowing region and the kill
markers to get out of sync, which prevents 'org-capture-finalize' from
correctly cleaning the target buffer when aborting the capture.

Setting the kill end marker insertion type fixes this.
