lib/sh/util.sh: command(): perform echo_run_prep itself instead of requiring echo_run to be added in an alias. echo_run_prep will not be performed if limit_stderr_cmd() has performed it already outside the limit_stderr section. this requires using `builtin command` instead of "command" when you don't want the echoing (such as in include_guard_var()).
