Description

It would be convenient in some cases to print the "lfs getstripe" fields in hexadecimal, for example using "lfs getstripe --hex -i /path/to/file" to print the starting OST index in hex.

The "x|xattr" option already exists in setxattr to set the foreign attribute data, and should not be used as a short option for getstripe, just the long "-hex" option.
