m-bib bug?

[ishamid <ishamid@lamar.colostate.edu>]

Dear posse,

Some settings of \setupindenting[] cause the first line created by 
\placepublications to be offset to the left; is this a bug? is there a 
workaround?

(And thank you Taco/Hans for helping me with my ``sneaky'' accent 
redefinitions!)

Best
Idris
