bugfix: lib/sh/util.sh: sed: must use alias instead of function because function causes segfault in redir() subshell when used with make.sh make() filter (may be bug in bash?). this involves translating `unset LANG` to `env LANG=` (`env -u` to unset a var isn't supported on Mac, but fortunately sed treats LANG="" the same as unset LANG).
