MercurialEclipse 184.108.40.206005170012 mercurialeclipse.feature.group
I'm not sure how it got into this state, but a file is changed in a project and the change decorations are not shown in the parent folders and project.
I restarted a couple of times and did not do anything else and they still don't appear.
Also, one time I restarted and there were no text decorations at all (no revision number, no "hg status pending"). There was the small cylinder indicating the files were under source control (I think).
