It was my pkgsrc partition, so I gave up and ran newfs.  Arguably, I
should have saved distfiles, but nothing else on it was worth
preserving.  -n might have helped -- I could mount the file system
read-only -- but fundamentally, the disk was confused.  I ran fsck on
it, and fsck was suggesting assorted negative numbers for various
values...  (Sorry, I didn't note what they were.)
