Interesting idea.  It wastes memory by allocating the argument vector
twice, but for most call-sites this won't be noticeable.  I suspect it
might fit at least some of the use cases for run_command_l_opt() better,
e.g. those that previously used a strvec or that need some flexibility.

Do you mean run_command_v_opt()?
