Patch Set 1:

I put the comments in bug 317376 (should have added that to the commit)

https://bugs.eclipse.org/bugs/show_bug.cgi?id=317376

Steps to Reproduce:
open a resource under EGit control
Go to 'history' view
Select two resources
Select 'compare with each other'
Note the title of the compare page is the name of the resource + full commit
reference for the two trees

Perhaps this needs to be changed in multiple places?
