Tidy: new-XXX-tags parameters in config

Dear Dave,

thanks a lot for your work on HTML Tidy utility. I find it extremely useful
for all HTML Developers.

I use it for IE 5.0 content. Due to IE 5.0 HTML extension (e.g. XML tag for
Data Islands, build-in behaviours etc.) it is necessary to use new-XXX-tags
parameters in Config file. It seems to me that they don't work correctly:
1. If I place anything after new-XXX-tags parameter in config file, this
added params are ignored. 
2. I cannot force Tidy to accept new-XXX-tags parameter values. A "<bbb> is
not recognized" error occurs.
Here is an example:
--------- config.txt:
 <<config.txt>> 
-------- source HTML
 <<pom.htm>> 
----------- Command line:
tidy.exe -config config.txt pom.htm
------------ Error file:
 <<err.txt>> 
------------ Tidy Version

Please notice "show-warnings: no" param which, placed after
"new-blocklevel-tags: bbb", is ignored.

Where am I wrong? Thank you very much for any hint.
