Dominik Psenner commented on LOG4NET-580:
-----------------------------------------
I was on a wrong track. There already are a few tests that I successfully broke
with my change, to name them all:
* LoggerNameCanConsistOfASingleDot
* LoggerNameCanConsistOfASingleNonDot
* LoggerNameCanContainSequenceOfDots
It looks like a guesswork was already implemented in the past. Therefore I'm
adding a few new tests:
* LoggerNameCanConsistOfANameStartingWithADot
* LoggerNameCanConsistOfANameEndingWithADot
I still have to figure out how to make that one work without rewriting the
UpdateParents() method from scratch. Stay tuned. :)
