pseudo initial empty commit and tag for git-log and git-describe?

pseudo initial empty commit and tag for git-log and git-describe?

[Nguyễn Thái Ngọc Duy]

I'm still uncomfortable with git-log -p unable to show the first
commit (git-whatchanged too). Also git-describe refuses to work
without any tag. I'm thinking about adding a pseudo empty commit
together with a tag so that these commands work. The commit and tag
will be created at runtime. They do not actually exist in the object
database. I haven't thought about how to implement it yet.
Any other ideas?

you can use git log -p --root  to also display the root commit.

Both of those work fine with "--root". That option tells git: "I'm 
interested in the root patch too".

It might make sense to have "--root" be the default, but the problem is 
that for projects like the Linux kernel where the first commit is a big 
import, showing it as a patch simply doesn't make sense.

So it would have to be a per-repository decision, depending on whether the 
repo considers the first commit to be an import or not. Maybe a git-config 
option?

Now, that's arguably a real bug. You should be able to describe any 
commit, and if there's no tag that is reachable from it, the "description" 
should probably just be the SHA1 of the commit.

(Side issue: we should probably also accept the output of "git describe" 
as a revision name, since it's a bit silly that you can ask git to 
"describe" a revision, but then git can't actually use the description 
itself ;)

Thanks. I didn't know about --root.
