Hello
When using
#+STARTUP: hideblocks overview
blocks are not hidden. With
#+STARTUP: hideblocks nofold
they are.
You can test with
#+STARTUP: overview
###+STARTUP: nofold
#+STARTUP: hideblocks
* title
#+begin_src emacs-lisp
code
#+end_src
I've tracked this down to the use of
(move-beginning-of-line 1)
in org-at-block-p. Replacing that with
(goto-char (pos-bol))
fixes the issue.
Debug statements revealed that
(move-beginning-of-line 1)
moves from the beginning of the block to the preceding line so that
(looking-at org-block-regexp)
no longer succeeds.
You might want to look into other uses of move-beginning-of-line.
Cheers,
Jonas
