Proposal

git-svn-id: https://svn.apache.org/repos/asf/tomcat/tc6.0.x/trunk@1560823 13f79535-47bb-0310-9956-ffa450edef68
Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=56029
Regression in fix for BZ55198 broke parsing of some ternary expressions
Align tc6 implementation with that of trunk (diff to trunk is easy to review)
