These functions are called in sequencer.c, which is part of
libgit.a. This makes libgit.a potentially require builtin/merge.c for
external git commands.

I made some unrelated changes in sequencer.c and this problem shown
up. merge-recursive.c is probably not the best place for these
functions. I just don't want to create merge.c for them.
