Dear diary, on Wed, Dec 07, 2005 at 10:39:43PM CET, I got a letter
where Jonas Fonseca <fonseca@diku.dk> said that...

Huh. The code in sha1_name.c speaks differently and it works as well:

	$ git-rev-parse b1fc
	b1fcca45069d4f6b00a9ac7136be4268d09fd6b9

VI has two modes: the one in which it beeps and the one in which
it doesn't.

I had this one testcase:

	~/src/elinks/0.11 > cg-object-id --verify e6b6
	cg-object-id: unrecognized option `--verify'
	~/src/elinks/0.11 > cg-object-id e6b6
	e6b65b543108bfeb95ea24978112b46e34cfde87

Could it have something to do with the local packing?
