Side note. It would be awesome if you could make parse_options() (or a
new function) do the reverse process: given a 'struct option' with
valid data, spit out argv_array. Less worrying about git-grep having
new option but not passed to subgrep by accident. You can have a new
flag to tell it to ignore certain options if you don't want to pass
all.

It indeed would be awesome.  I do not offhand know if it would be
feasible or the result is easy to use without mistakes, though.
