right, you traced back to the right macro! but before and after were never 
supposed to be used for rules, just for fills and so; what you see in 
action is an interference with the way teh line is build. Now after and 
before work on the whole line; I can probably add some hooks per text, and 
actually i've played with that, but we will run into complicated (and hard 
to explain) situations with regards to empty/high/stop situations; this is 
why the best way is use backgrounds for rules (see earlier mail); i can add 
before/after hooks for situations where there is content (this would permit 
quick and dirty styles).

\setupbackgrounds[text][text][...]

PS. Some limitations originate in the time when hash tables were small; 
every key added to a text area results in 25 new hash entries, so this is 
why at the moment some settings are not on a per areas basis
