Hello,
I have encountered two related misbehaviors in the parser/exporter.
The first manifests if you type the following line into an org-mode
buffer and execute M-: (org-element-context) with point on the ‘f’; the
result is a subscript object, whereas I would have expected an
underline:
'_foo_
I think both possibilities are returned by
org-element--get-next-object-candidates, and subscript “wins” because it
precedes the other in the list. I’m not sure how this should be
addressed, but maybe Nicolas knows.
I encountered the second issue when trying to hack around the first by
setting org-use-sub-superscripts to '{}. It seems this variable is not
considered by the parser. I think the attached patch fixes this issue.
Thanks,
