Okay, I have looked at that again this morning and I've spotted one
tiny issue: specifying --progress with --skip-checksums does not
really make sense.

Ignoring entries with a bad size would lead to incorrect progress
report (for example, say an entry in the manifest has a largely
oversized size number), so your approach on this side is correct. The
application of the ignore list via -i is also correct, as a patch
matching with should_ignore_relpath() does not compute an extra size
for total_size.

I was also wondering for a few minutes while on it whether it would
have been cleaner to move the check for should_ignore_relpath()
directly in verify_file_checksum() and verify_backup_file(), but
nobody has complained about that as being a problem, either.

What do you think about the updated version attached?
