Ideally, we need two sets for each arrow:
	
   % a more or less normal TeX set with and extra
   % tail section:
   <arrow head with straight connecting bar>
   <straight bar>
   <arrow tail end>

   % a set for CM transform based macros:
   <arrow head totally without bar>
   <tapered arrow shaft>
   <arrow tail without shaft>

and those (of course) for all eight standard arrows
(four directions * double shafted)
