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.
