[RESEND PATCH] bisect: use oid_to_hex_r() instead of memcpy()+oid_to_hex()

[René Scharfe]

Write the hexadecimal object ID directly into the destination buffer
using oid_to_hex_r() instead of writing it into a static buffer first
using oid_to_hex() and then copying it from there using memcpy().
This is shorter, simpler and a bit more efficient.
