-""" This extension provides direct access
-It is the ability to refer and access hidden sha in commands provided that you
-know their value.
-For example hg log -r xxx where xxx is a commit has should work whether xxx is
-hidden or not as we assume that the user knows what he is doing when referring
-to xxx.
