Right.
Upon debugging further, to my great surprise, I found the following
comment in ox.el:
;; Export snippets never return a nil value so
;; that white spaces following them are never
;; ignored.
(and (eq type 'export-snippet) "")
and then even a test:
;; Ignored export snippets do not remove any blank.
(should
(equal "begin end\n"
(org-test-with-parsed-data "begin @@test:A@@ end"
(org-export-data-with-backend
tree
(org-export-create-backend
:transcoders
'((paragraph . (lambda (paragraph contents info) contents))
(section . (lambda (section contents info) contents))))
info))))
The test was added in the commit
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=a6d9fd82e
Back-end developers should pay attention to the fact that white spaces
before and after an ignored export snippet now are accumulated in the
output.
I have no clue about the rationale of this special behaviour - it dates
back to the days when Org export was merged. It is also not documented
anywhere, AFAIK.
