It would be convenient to allow specifying a range of OSTs to find objects on, like "lfs find /mnt/testfs -type f --ost 8-15". Currently, one has to specify all of the OSTs in a comma-separated list like "... --ost 8,9,10,11,12,13,14,15", which can be inconvenient for large OST lists. Using the bash range syntax like "{8..15}" doesn't work because this will expand to a space-separated list of indices.
