Revision 1559401

Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=56029 a regression in the fix for https://issues.apache.org/bugzilla/show_bug.cgi?id=55198
Remove the code to skip whitespace from the 'simple'EL parser. It is far simpler to retain the whitespace than it is to teach this simple parser parser when to insert it. This also has the benefit that the EL should remain unchanged.
Add a number of test cases for BZ 56029
