In patch-id.c, get_one_patchid uses a fixed 1000-char buffer to read a line.[1]
This causes incorrect results on longer lines. Pasted below is a git commit
(from git show) that demonstrates the problem. The result of running git
patch-id on this commit is:
9220f380851be9cab1a760430e3be096dcbee8c6 9b96b6fde8f7df791a1490ae18e1fa75fbab3262
