Ok, the strategy part is now behind us, but I have this slight suspicion
(I didn't look at the code nor tried it out myself---I don't have time to
do this myself today) that using this codepath might result in a corrupt
cache-tree, whose entries point at a section of the index it covers as a
subtree of the whole project but with incorrect counters or something like
that.  It would be good to make sure this "just ignoring i-t-a" is doing
the right thing not to the resulting commit, but in the resulting index as
well, before we go forward with this change.

I looked a little bit and I think i-t-a entries do not break
cache-tree. CE_REMOVE ones might though because they are taken into
account in entry_count field, but they are not written down to file.
Will look into it tonight.
