You are right, both are needed.  Maybe org-mode (the function, i.e. the
code executed when opening an org-mode file) should look for BIND keywords
and set local variables according to them.  Otherwise people might need
the same entry in BIND and the local variables block.  WDYT?

(Of course, it would be even better if we could convince ourselves that
local variables will work 100% of the time for export – then the use
case for BIND would be restricted to setupfiles.  I tried to see if I
could convince myself of this, but quickly got lost.)

OK.  I will push a patch to master with your suggestions.
