Uninline prefixcmp()
Now the routine is an open-coded loop that avoids an extra strlen() in the previous implementation, it got a bit too big to be inlined. Uninlining it makes code footprint smaller but the result still retains the avoidance of strlen() cost. Signed-off-by: Junio C Hamano <gitster@pobox.com>
