That's odd. Wine-devel was CCed on the mail. Maybe the image
attachment made the email too large, and it was filtered.

They'll have to be sent to wine-patches anyway for proper review.

Ah, I sort of skipped over the commit messages, sorry. I would just
remove "no effect" from the third commit message, because there can be
an effect sometimes, it's just wrong. You could also remove the word
"error" from the first two.

The messages don't sound completely natural in English to me, but
there is also limited space, and I can't think of a way to make them
more natural without also making them longer or less descriptive.
