I prefer that the switch still be before. But if it is missing, 'max' should 
be a reasonable default.
So the syntax becomes:

      btrfs resize|-r [[+/-]<newsize>[gkm]|max] <filesystem>
               Resize the file system. If '-r' is missing or 'max' is passed, 
the filesystem
               will occupe all available space on the device.

My command "btrfs" is only a front end which call library functions. It 
doesn't implement the scan engine.
But I agree that a "small" tool which performs the scanning only function is 
reasonable.
