Btrfs devel - Jul 2014 - How to skip "looping a lot" question of btrfs restore 3.15?

Hi together,
In the current HEAD (3f11e516db629f7a662bfd6376231817b4e34cc9) of
https://github.com/kdave/btrfs-progs.git (I assume this list is the
right address because I got some hints to the project from here) the
btrfs restore subcommand asks often (up to 100 time during restauration
of 400 GB)

    We seem to be looping a lot on /a/path/to/our/precious, do you want
to keep going on ? (y/N):

which can't be suppressed with the `-i` option (which might be right
because it's technically not an error), but I can't see how to get
around this. Am I missing something? Otherwise it would be nice to have
an extra option maybe with an argument how often "we" are looping on a
file before the command asks for interaction.

Best regards,
Karl-P. Richter
