The changes to org-overview in the commit c3748fcd80ec53dc9b0db6e2ad17be6b14dd3bb9 make it impossible to use org-global-cycle (i.e., org-overview) in non-org buffers, such as Auctex.
The problematic line is 6231: (if (re-search-forward org-outline-regexp-bol nil t) org-outline-regexp-bol is hard-coded to match only the beginning of outlines in org-buffers: (defconst org-outline-regexp-bol "^\\*+ ") The old line in org overview, by contrast, looked for the beginning of an outline line: (if (re-search-forward (concat "^" outline-regexp) nil t) Would it be possible to revert to the older, more generous construction of the regexp (so that it can vary by mode/buffer)? Thanks! Matt
