  Add setenv_ prefix to foreign_option funtion so it is more obvious what
it does. Move it further up within options.c, so it is defined before
all future callers. Also declare all argv strings const.

Slightly less trivial, but "git show --color-moved=zebra" helps
visualize that it's indeed moved 1:1 and just gets a new name.

Your patch has been applied to the master branch.
