Not yet.

I could reproduce it several times now:
In a emacs repo handled by git:
1) Apply a stash or make some changes.(I use here cl-macs.el)
2) make some more changes, save buffer twice or more.
3) C-x v u (revert changes)
Now in the zone where the changes was, cursor is jumping several lines
when doing C-n/p.
Indeed, if I set cache-long-scans to nil, and reproduce exactly the same recipe,
the bug is not happening.
