Re: [IGNORETHIS/PATCH] Choosing the sha1 prefix of your commits

Heh, there's one other practical downside I can think of...

If you create a bunch of commits with the same 8-hex-character prefix
then suddenly the "git describe" logic for using the first 7 commit ID
characters gets a whole lot less useful.

In the sense that you need to cut and paste a lot more characters, you are
correct that it would make it less useful, but if you are talking about
uniqueness, you are mistaken.

The rule is not "using the first 7 hexdigits", but is "using as many
hexdigits to make assure uniqueness, but use at least 7".
