I think of that as a new file that extracts a piece of an old file.

New.

Similar to "acks.rkt" --- new files that are a small pieces of old
files.

This strikes me as actual history loss (due to many changes in a small
file).

New.

Mostly new, since it's a merger of pieces of two files into one.

Not worth tracking.

Some are truly gone, and some are covered above. I don't understand why
most of them are in the list, though, since `git follow --log' on each
new location works for me (for the handful that I tried).

Well, exactly.


So, for the big reorganization of the tree, we seem to be losing
history (that separate move and change commits would clearly preserve)
on only a couple of 40-line files. I am more than satisfied with that
result, compared to what we get from day-to-day use of git --- and
particularly compared to the pain of trying to stage moves before edits
in the reorganization.
