Got it. This is a bad side effect from the `cmp' test in install rule.

If the man page gets modified, but the change is not noticeable in
either cat or html pages; neither of them will be updated in dest dir,
only the source page. In that case, the cat page will be older than
the man page ... triggering the postinstall warning and fix.
