Looks nice.  I agree with Petr's comment that separating core part
and Cogito part would be good, and I would appreciate if you
pushed the core part documentation to Linus as well.

Some nitpicks and notes on your core part description.

DG>  commit-tree
DG> -   commit-tree <sha1> [-p <sha1>]* < changelog
DG> +   commit-tree <sha1> [-p <parent sha1>...] < changelog
 
The above does not describe what commit-tree expects.  It wants

    commit-tree <tree-sha1> [-p <parent1 sha1>]* <changelog

That is, you need -p before every parent.  I however think what
coommit-tree does here this aspect is wrong, unless Linus has
plans to give parameters other than parent IDs to commit-tree
later.  Even if that is the case, those non-parent things can
have their own -flag in front of them so not requiring -p would
be a good change.  I'll ask opinion from Linus on this (I just
sent out a patch).

DG> +A commit object usually has 1 parent (a commit after a change) or 2

DG> +2 parents.

I'd rewrite the "or 2 parents..." part to "up to 16 parents.  More
than one parent represents merge of branches that led to them."

CRs are kept.  It removes '\n' (which is not necessarily LF).

DG> +diff-cache

And the option to use working tree is not having the --cached
flag you describe later.  Please also update the usage at the
top as well:

        diff-cache [-r] [-z] [--cached] <tree/commit sha1>

DG> +In the special case of the file being changed on disk and out of sync with 
the cache, the sha1

Is the description truncated after "the sha1"???

DG>  ################################################################
DG>  diff-tree
DG> -   diff-tree [-r] [-z] <tree sha1> <tree sha1>
DG> +   diff-tree [-r] [-z] <tree sha1> <tree sha1> 

This command can take commit ID in place of tree ID.
