[nhibernate-development] Proposed refactorings - best way to submit?

[Gerke Geurts]

I have refactored part of the custom SQL processing code in the process of 
trying to get more meaningful error messages for problems with 
custom/native SQL mappings. A pull request resides at 
https://github.com/nhibernate/nhibernate-core/pull/161. Should I generate a 
JIRA ticket as well?
