cogito - how do I ???

Hi all.

While trying to get up to speed on cogito/git I stumbled across
a few things that I at least did not find available in cogito.

1) Something similar to "bk changes -R". I use this to see what has
happened upstream - to see if I really want to merge stuff.

2) Export of individual patches. "bk export -tpatch -r1.2345"
I have nu public git repository yet so I have to feed changes as
plain patches. Browsing cg-* I did not find the command to do this.

I do try to avoid having to develop my little army of shell scripts,
and due to this I have avoided the git- commands for now.

Any help appreciated,
	Sam
