I agree that if you know Git internals -- and you and me do -- it comes in 
_right_ handy to know the 100+ commands with many options by heart.

However, my point was about telling users, especially new ones.

For example, I would _never_ suggest the following workflow to a n00b 
because it would be confusing:

	$ tar xvf <xyz>
	<try to compile>
	<fix a compile error>
	<fix other things>
	<oh, I could contribute the fixes!>
	$ git init
	$ git remote add -f origin <url>
	$ git read-tree <that-tag>
	$ git status
	$ git add -p
	$ git commit -s
	<repeat until there are no changes left>
	$ git rebase -i origin/master
	$ git format-patch -n origin/master

Even if this is something I did at least a handfull times myself.

Ciao,
Dscho
