I think this is due to a subtly misleading file format variation. If you look at ‘export-paths’, it does:
while there are files to write
write-long-long 1
export-path file
write-long-long 0
‘restore-file-set’ does the opposite, which is to read that long-long to
determine whether there’s data coming up, and then to call
‘restore-file’.
HTH!
