Hi Bastien,

I'll try to find a different mail client next time.

I don't really understand why `run-hook-with-args-until-success' is
needed here.  Or `org-export-format-drawer-function' returns a string,
or it returns nil, in case we fall back on `org-export-format-drawer'.

My thought was that you could have multiple hooks in org-export-format-drawer-function and each one could be checking for things like "is this html export", "is the drawer name == PROPERTIES" and could decide to take action and return a string, or perhaps take no action, return nil, and let another hook have a shot at the drawer.  The other thing with funcall here is that if you use add-hook to add your function to that hook it creates a list of functions, and when funcall is called on a list of functions instead of an individual function it is an error.

Best,
