In attachment is a patch making tests of the previous mail
(id:"87wqvtrxcp.fsf@konixwork.incubateur.ens-lyon.fr") pass.

It adjusts org-open-at-point to have plain links handled the same way
bracket links are. It allows plain links to be followed if the cursor is
before the link while still on the same line.

I also got rid of dangling parenthesis as suggested by
Nicolas. Personally, I think it is easier to read with dangling
parens. Could you explain what is wrong with them?

Thanks for your attention.
