This can take a lot of memory. I decided to violate the usual rule in
git-annex that it operate in constant memory no matter how many annexed
objects. In this case, it would be hard to be fast without using a big
map of the location logs. The main difficulty here is that there can be
many git-annex branches and it needs to display a consistent view at a
point in time, which means merging information from multiple git-annex
branches.
I have not checked if there are any laziness leaks in this code. It
takes 1 gb to run in my big repo, which is around what I estimated
before writing it.
2 options that are documented are not yet implemented.
Small bug: With eg --when=1h, it will display at 12:00 then 1:10 if the
next change after 12:59 is then. Then it waits until after 2:10 to
display the next change. It ought to wait until after 2:00.
