Thanks, these are interesting ideas!

Single-letter options are global. As this is used by only one command,
it should use local double-dash options for that.

Remember:
   port [global-options] action [local-options] ...

I suggest to use "port size --human-readable". Note that this can be
abbreviated already up to --h if it is unambiguous.
