Tabs remain marked as modified after switching branches

[adamreisnz]

@iolsen this is probably related to #306

When I have some files open that exist in branch A but not in branch B, and then if I switch from A to B to check some code, all my open tabs are marked as modified, because the files no longer exist on the disk. This is correct, however, when I switch back to branch A, the tabs are all still marked as modified, and I have to "save" all the tabs, even though it's a no-op because nothing actually changed.

Any thoughts how we could address this?

This also occurs when doing something like an interactive rebase.

I believe this is a duplicate of atom/atom#14765, the fix for which will ship this week.
