FWIW cmd_merge_recursive is used to handle four different commands.

$ git grep -F -e cmd_merge_recursive
builtin.h:extern int cmd_merge_recursive(int argc, const char **argv, const char *prefix);
builtin/merge-recursive.c:int cmd_merge_recursive(int argc, const char **argv, const char *prefix)
git.c:          { "merge-recursive", cmd_merge_recursive, RUN_SETUP | NEED_WORK_TREE },
git.c:          { "merge-recursive-ours", cmd_merge_recursive, RUN_SETUP | NEED_WORK_TREE },
git.c:          { "merge-recursive-theirs", cmd_merge_recursive, RUN_SETUP | NEED_WORK_TREE },
git.c:          { "merge-subtree", cmd_merge_recursive, RUN_SETUP | NEED_WORK_TREE },

What will be the output from

 $ git merge-subtree -h

after this change?

Changes like these, while nice, would make more sense as a separate
patch.

Hope that helps,
