OK - just tested this last point, by creating a repo with 5 revisions (0 to
4) and corrupting rev 2. The dump file terminates after outputting the
revision properties, but before outputting any actual data from that
revision.
Basically, what happens is that, when the error occurs, an error message
goes to stderr and the dump process terminates, so whatever is written up to
that point is retained. As you say, an incremental or partial dump that
doesn't include any bad revisions will work fine.
