...that proved surprisingly tough to troubleshoot.

I got the following output from my working copy.

`\r` is a perfectly legal *roff escape sequence, but one generally never
sees it in man pages.  In that case, the input line in question was at
the top of the "page" in continuous rendering mode, and so the attempt
at a reverse vertical motion did indeed put the drawing position above
the top of the page.

grepping reveals no other occurrences of '\r' in the man-pages corpus.
