I wonder if it would be nicer to use `error()` instead so we could do a better job at cleanup.

Some of the command line options in `cmd_pack_refs()` require us to allocate memory. This memory is never released and thus leaking, but we paper over this leak by declaring the respective variables as `static` function-level variables, which is somewhat awkward. Refactor the code to release the allocated memory and drop the `static` declaration. While at it, remove the useless `flags` variable.
