Btw, I run these in parallel on inboxes I have:

N=$(nproc)
find ~/v2/*/git/ -type d -name '*.git' -print0 | xargs -0 -P$N -n1 sh -c \
	'GIANT_INBOX_DIR=$1 perl -I lib -w xt/cmp-msgview.t' --
find ~/v1/ -type d -name '*.git' -print0 | xargs -0 -P$N -n1 sh -c \
	'GIANT_INBOX_DIR=$1 perl -I lib -w xt/cmp-msgstr.t' --

And the main differences I see are minor:

* trailing whitespace may still be different for broken messages
  missing epilogues (MIMEDefang, or some old gnus + GPG)

* trailing whitespace differences for header extraction
  (Eml strips all trailing spaces, not just LF/CRLF)

* empty parts of multipart messages are skipped for efficiency
