"Unsaved Changes" count is off by one if selecting a range

[chris-erickson]

Single select

• Select 1 Item, delete it, "1 unsaved change"
• Select 1 more Item, delete it, "2 unsaved changes"
• .. repeat as neccessary

Multi-select

• Shift Select 2 Items, delete them, "3 unsaved changes"

It seems to always have 1 too many items if a range select is used, but not if you perform the actions one at a time.
