Oops. You're absolutely right. I forgot that we were looking at the body.
So one has to match on (.|^[ ]) instead of just . as in a header.
Sorry for missing that.
Too dang bad these multi-part chimeras can't be split into components with
some variation on formail -s so that they can then be processed as individual
messages, and each part's inner header lines will look like a header.

No, not yet.
