It's not a bug, it's a feature.  Hardlinks on FAT don't exist.  They
have been faked in 1.5 by copying the file.  The decision was made a
coupld of weeks back to drop this fake since the application should know
that the underlying filesystem is not capable of creating hardlinks.
It's in the mail archive and in the "What's new" section of the User's
Guide.
