revlog: avoid exposing delayed index entry too widely in non-inline revlog

Before this change, the index entry would be seen as "appended" to the data
file. It did not hurt too much as there are never accessed for reading, but this
was odd. So lets stop doing so.

#ifndef HG_BDIFF_H
#define HG_BDIFF_H

#include "compat.h"

struct bdiff_line {
	int hash, n, e;
	ssize_t len;
	const char *l;
};

struct bdiff_hunk;
struct bdiff_hunk {
	int a1, a2, b1, b2;
	struct bdiff_hunk *next;
};

int bdiff_splitlines(const char *a, ssize_t len, struct bdiff_line **lr);
int bdiff_diff(struct bdiff_line *a, int an, struct bdiff_line *b, int bn,
               struct bdiff_hunk *base);
void bdiff_freehunks(struct bdiff_hunk *l);
