lib/sh/util.sh: sed: changed it to an alias so it will also be expanded when passed to an external command (like in_place) that can only run an executable, not a shell function (this occurs as long as the external command is defined as an alias which ends in space, to alias-expand the next word). added associated $sed_cmd var for cases when there is no alias wrapper around the external command, and the literal alias body must be used instead.
