[svn-r24587] 1) Removed the workaround that forced rank 0 to do the abort call, as lower layers now working 
properly when abort/updates occur in various orders across nodes and there are no more dangling 
open objects that caused file close to fail previously.  

Also removed the -w option that toggled the workaround off.

2) Changed output for 2D datasets to use row: not r: to indicate row number because r: was
messing up my post-processing grep for specific ranks.
