[PATCH v1] pack-protocol: fix maximum pkt-line size

[larsxschneider@gmail.com]

From: Lars Schneider <larsxschneider@gmail.com>

According to LARGE_PACKET_MAX in pkt-line.h the maximal length of a
pkt-line packet is 65520 bytes. The pkt-line header takes 4 bytes and
therefore the pkt-line data component must not exceed 65516 bytes.

This patch was part of my "Git filter protocol" series [1]. Stefan
suggested to submit this patch individually as it is not strictly
required in the series [2].

Thanks,
Lars
