needless code

[da0ka]

lz77.c: maybe line 374 and line 379 is needless code.

i++;
while (i + ZOPFLI_MAX_MATCH <= inend && memcmp(&in[i], &in[i - 1], ZOPFLI_MAX_MATCH) == 0) {
	ZopfliStoreLitLenDist(lls + ((leng - symtox(lls)) << 9), ZopfliGetDistSymbol(dist) + 1, store);
	i += leng;
}
i--;

after(rewrite line 375, 376)
dist==1, so ZopfliGetDistSymbol(dist) is 0

while (i + ZOPFLI_MAX_MATCH < inend && memcmp(&in[i+1], &in[i], ZOPFLI_MAX_MATCH) == 0){
	ZopfliStoreLitLenDist(lls + ((leng - symtox(lls)) << 9),1,store);
	i += leng;
}
