I'm restoring resize capability (albeit only via a library)
that was present in parted-2.3/2.4 and earlier, so one way to check
is to actually use an older version of parted on HFS+/HFSX file systems.

If you read the code or documentation, you'll see mention of
both HFS+ and HFSX, in addition to HFS.

Or you can take a wild guess:
Would people be complaining about removal of this functionality
(and would I be taking the time to restore it) if it affected
only some type of file system that no one uses anymore?
