bug#21818: 24.5; org-set-tags-to indentation problems when called programmatically

[mail]

1. Start emacs with emacs -Q
2. Evaluate the following:

(require 'org-mode)

(defun bad-indent ()
  (interactive)
  (insert "* ")
  (org-insert-link nil "http://www.example.com/foo/bar/baz/qux/abc123f56789" "something")
  (org-set-tags-to '("foo")))

3. Switch to an empty buffer
4. M-x org-mode
5. M-x bad-indent
6. The result looks like the following (except with an actual hyperlink):

* something	:foo:

This indentation is incorrect. If you follow the steps for `bad-indent'
interactively (or even using edebug), the indentation looks like:

* something								:foo:

Digging in some more, it looks like the problem is the `current-column'
call in `org-set-tags' (where it says 'setq c0 (current-column)', on
line 14620 of org.el in my distribution). With some instrumentation,
`current-column' seems to be giving different values in interactive mode
than programatically; I'm guessing it has something to do with the long
link target causing the value to be different.

Are you sure this isn't a problem with Org mode?  If not, can you tell
why you think so?

Thanks.

Org mode has its own bug tracker, AFAIR.

If the Org developers say it's a core bug, please come back here (or
they should), with data that shows how to reproduce the problem,
ideally without Org at all.

Thanks.

P.S. Your email bounces, so sending me a private email is not very
wise...

OK, I'll submit there. Thanks!

Oops, sorry about that and thanks for the heads up.

Nope, just a mailing list AFAIK. Assigning something to the debbugs
org-mode package (which I already did for this report) sends stuff there.
