summary:

When a file is removed, it is not properly logged in the hg log.  A removed file
should also appear as a changed file in the log

Steps to reproduce:

1) create file "filename"
2) $ hg add filename
3) $ hg commmit filename
4) remove file "filename"
5) $ hg commit
6) $ hg log -v 

RESULT: a log entry with an empty "file:" section
EXPECT: a log entry with the "file:" section listing the file removed
