Fix rule for token position example

[mluszczyk]

The sample rule for CIdent has a "|" in it by mistake. The error makes CIdent accept empty strings which causes problems and raises the following warning:

Warning :
The following tokens accept the empty string:
CIdent
This is error-prone and will not be supported in the future.

Please also update the "BNF Converter Tutorial" page (http://bnfc.digitalgrammars.com/tutorial.html). The following line appears there:

position token CIdent (letter | (letter | digit | '_')*) ;

Thanks again! I fixed it in the repo. I am not sure how to update the web page though. This is maintained by Aarne's company. @aarne, Thomas: over to you! Best, Andreas
