==================== Summary ====================

Name: ShoutCore-eem.84
Author: eem

Ancestors: ShoutCore-mt.83

Shout robustness.  If anything goes wron with source file access (recursive errors in the debugger, etc) then method getSource may not answer sufficient text and a bounds violation can occur in Shout.  This prevents that.
