This is a nice cleanup, but it does not belong in this patch.

I was thinking the same thing right after I sent it off.

To use the append_option() function, you need to make sure that the argv
has enough space, so I suggest adding another NULL to argv_repack[].  This
is enough, since you only ever add one option.  But you should mention it
somewhere, probably above the definition of argv_repack[].

Shouldn't argv_repack have space for MAX_ADD (10) items?

append_option() is already used with argv_repack when --aggressive is
used.

Other than that: I think your patch makes tons of sense; much better than
what I tried to cobble together with the cyclic alternates detection.

Thanks.
