Log: 640 number_to_scaled_string is duplicated in several commands illumos/illumos-gate@0a0551200ecbcd4f1b17560acaeeb7b6c8b0090e https://github.com/illumos/illumos-gate/commit/0a0551200ecbcd4f1b17560acaeeb7b6c8b0090e https://www.illumos.org/issues/640 du(1), df(1m), ls(1), and swap(1m) all include a copy (it appears literally copied) of the 'number_to_scaled_string' function in their source. This should be moved to a shared library and all 4 commands should use this instead.
