OK, I can understand that but if, as I now see in 13.2, both TITLE and
EXPORT_FILE_NAME are export settings, why does it behaves as I expect
for TITLE (the title I get is indeed 'bart') but not for
EXPORT_FILE_NAME?

I don't understand that: what about the line '#+EXPORT_FILE_NAME:
bar.pdf'??

Yes, of course; if it is a comment, it is as if it were not here at
all, correct?

How about adding a sentence in 13.6, perhaps in the footnote?
Something like "Also note that, as mentioned in 13.2, export
settings, being global, take precedence over the 'COMMENT' keyword."

Finally, I'd appreciate a "SUPERCOMMENT" keyword, which would be
equivalent (when exporting) to removing the tree altogether (or, as I
understand, prepending '# ' to each line of the tree).
