Emacs 29.1, org-agenda and SCHEDULED entries

[Christian Barthel <bch@online.de>]

Hi,

while upgrading from emacs 28.1 to 29.1, my org-agenda stopped working.
The message in the echo area was:

--8<---------------cut here---------------start------------->8---
    Search failed: "\\<SCHEDULED: *<\\([^>]+\\)>"
--8<---------------cut here---------------end--------------->8---

The search seemed to fail in an old org file:

--8<---------------cut here---------------start------------->8---
  * someentry
    SCHEDULED: [2017-12-12 Tue 17:42]
--8<---------------cut here---------------end--------------->8---

Not sure why I've used an inactive timestamp there but it shouldn't
be a problem I guess?

As a workaround, I have updated the `org-schedule-time-regexp` to
match the brackets as well:

--8<---------------cut here---------------start------------->8---
(setq org-scheduled-time-regexp
  (concat "\\<" org-scheduled-string " *[[<]\\([^]>]+\\)[]>]"))
--8<---------------cut here---------------end--------------->8---

With that new regexp, my agenda loads again without errors but
I do wonder:


Was/Is that change on purpose? (I haven't seen anything in the
ChangeLog)
