NPE at Revlog.getLocalRevision() #17

The issue seems odd as the only chance for NPE in Revlog#getLocalRevision is 
local file that doesn't exist. However, areTheSame above in the stacktrace is 
invoked only when file is known as 'Normal' in dirstate (moreover, even 
revision of the file is known from the dirstate parent). 

Added this request to keep track of couple debug changes made to the code to 
nail the issue down (HgWorkingCopyStatusCollector#checkLocalStatusAgainstFile 
got an extra check for file node existence)

Issue 18 describes the problem more thoroughly.
