Good question.

I'd probably say "last revision successfully dumped was rN" and then exit with
a non-zero code, leaving it to the admin to clean up the mess (i.e., to truncate
the dumpfile after the end of rN's data).

Unfortunately, since you dump to stdout, you can't do that seek+truncate yourself :-(

What if a file contains that line as part of its content?

(This could happen if somebody versioned a dumpfile. We do.)
