Re: [PATCH 0/2] xdiff: Remove unneeded members from xrecord_t and xdlclass_t

This series has a couple of cleanups on top of 'en/xdiff-cleanup-2'
that reduce the sizes of the xrecord_t and xdlclass_t. Unfortunately
they conflict with 'en/xdiff-cleanup-3' in seen, in particular with
db8a50ca6b9 (xdiff: don't waste time guessing the number of lines,
2026-01-02). I'm not particularly convinced that moving the call to
xdl_classify_record() out of xdl_prepare_ctx() in that commit is
a good idea, but if we decide that we do want to stop classifying
lines in xdl_prepare_ctx() we can start passing the hashes out in a
separate array rather than wasting space in xrecord_t.

Both patches look well reasoned and sensible.

It is unfortunate that the en/xdiff-cleanup-3 wants to pull these
fields in a different direction, but the topic has been dormant for
quite a while, so let's tentatively kick it out of 'seen' and see
how well this one does, until we decide how to consolidate the two
topics.  Thanks.
