The following is a patch to centralize the test for an active-enabled 
breakpoint.   This patch is in response to Daniel J's comments to split 
up the pending-breakpoint support patch.   With pending breakpoint 
support, the test will be modified to include a check for a pending 
breakpoint.  This will simplify reviewing the last of the patches 
required for pending-breakpoint support.

Ok to commit?
