New Revision: 40200

URL: http://svn.digium.com/view/asterisk?rev=40200&view=rev
Log:
In app_macro, changed the previously changed upper recursion depth limit to a variable, default of the original val of 7. MACRO_RECURSION is a channel variable that will override the limit, but until I can understand and fix why this limit is neccessary, I am not advertising this variable in the docs.
