Thanks for following up.
I've applied your patch after adjusting the log and a failing test,
then added two more tests to cover the new types of output lines.

Subject: [PATCH 1/2] md5sum: print a summary warning for improperly formatted
lines
And remove the now-superfluous totals from the other two warnings,
so the plurals will also work in other languages than English.
* src/md5sum.c (digest_check): Change as above.
* tests/misc/md5sum (check-quiet2): Adjust accordingly.
