Description Eric Safern 2004-01-27 04:11:44 UTC 
To be consistent with other tasks (such as the <input> task),
if a resultproperty is specified, and that property is already set, the exec 
task should not run at all.

This would make it easy to suppress an exec call programatically, and remove 
the ambiguity of the exec task trying to set a property that has already been 
set.
