Incoming Changes is showing a changelist for a commit made by me last week (so it shouldn't even be showing this in the first place) where files which existed before the commit and were merely modified are shown in the green color for added files. Invoking the diff shows an empty left-pane. The affected files seem to be files which were unmodified on my checked out branch so they had a HEAD revision number (e.g. 1.15) and the new revision after the commit has a branch revision number (e.g. 1.15.8.1). Files which were already modified on the branch and thus already had a branch revision number are correctly shown as modified in the changelist.
