Faster working dir revision calculation We used to use 'hg identity' to get a working dir revision. It shows the revision but also adds a '+' sign if some files were changed. For repository with a size of R# it takes around 5 minutes to understand that all files are unmodified and '+' sign is not needed. To update sources we don't use this information at all. Switch to 'hg parents' which takes around a second because it doesn't check if files were modified.
