Ah, but we'd still need to prepare individual bits in the child
structure (e.g. RUN_GIT_CMD vs .git_cmd) anyway.  Even though we may
not have to work with the flags, somehow we need to set it up.  So
it is not all that strong argument against the _l_opt().

The above assessment is primarily because I do not have too much
against RUN_GIT_CMD and friends, compared to setting the individual
members in the child_process struct.  Setting individual members in
the struct is more direct and it may be an improvement use
run_command() directly over using _v_opt() and _l_opt() variants.
