New Revision: 361522

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=361522
Log:
Don't add an empty MESSAGE_DATA(key) header if it doesn't already exist.

Doing Set(MESSAGE_DATA(key)=) would add an empty key header if the key
header did not already exist.  If it already existed it would delete it.

* Made msg_set_var_full() exit early if the named variable did not already
exist and the value to set is empty.
