I went with 0555 as the permissions changing only occurs to bin, sbin and lib, so there shouldn't be any files in there for editing in general anyway. Formulae can specify not to "clean" any particular file by reimplementing the skip_clean? function, in case some config file or what not ends up in there. Also committing cosmetic fix to pretty_duration function.
