Dear diary, on Mon, Apr 18, 2005 at 02:49:06AM CEST, I got a letter
where Herbert Xu [off-list ref] told me that...

Therefore the only conclusion I can draw is that we're only calling
update-cache on the set of changed files, or at most a small superset
of them.  In that case, the cost of the collision check *is* proportional
to the size of the change.

Yes, of course, sorry for the confusion.  We only consider files you
either specify manually or which have their stat metadata changed
relative to the directory cache. (That is from the git-pasky
perspective; from the plumbing perspective, the user just does
update-cache on whatever he picks.)
